2009-01-06UBIFS: do not use WB_SYNC_HOLDArtem Bityutskiy1-1/+8
WB_SYNC_HOLD is going to be zapped so we should not use it. Use %WB_SYNC_NONE instead. Here is what akpm said: "I think I'll just switch that to WB_SYNC_NONE. The `wait==0' mode is just an advisory thing to help the fs shove lots of data into the queues. If some gets missed then it'll be picked up on the second ->sync_fs call, with wait==1."

2009-01-04fs: symlink write_begin allocation context fixNick Piggin1-4/+5
With the write_begin/write_end aops, page_symlink was broken because it could no longer pass a GFP_NOFS type mask into the point where the allocations happened. They are done in write_begin, which would always assume that the filesystem can be entered from reclaim. This bug could cause filesystem deadlocks. The funny thing with having a gfp_t mask there is that it doesn't really allow the caller to arbitrarily tinker with the context in which it can be called. It couldn't ever be GFP_ATOMIC, for example, because it needs to take the page lock. The only thing any callers care about is __GFP_FS anyway, so turn that into a single flag. Add a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on this flag in their write_begin function. Change __grab_cache_page to accept a nofs argument as well, to honour that flag (while we're there, change the name to grab_cache_page_write_begin which is more instructive and does away with random leading underscores). This is really a more flexible way to go in the end anyway -- if a filesystem happens to want any extra allocations aside from the pagecache ones in ints write_begin function, it may now use GFP_KERNEL (rather than GFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a random example).

2008-12-31UBIFS: allow mounting when short of spaceArtem Bityutskiy1-11/+29
It is fine if there is not free space - we should still allow mounting this FS. This patch relaxes the free space requirements and adds info dumps. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix writing uncompressed filesArtem Bityutskiy2-1/+3
UBIFS does not disable compression if ui->flags is non-zero, e.g. if the file has "sync" flag. This is because of the typo which is fixed by this patch. The patch also adds a couple of useful debugging prints. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix checkpatch.pl warningsArtem Bityutskiy6-25/+25
These are mostly long lines and wrong indentation warning fixes. But also there are two volatile variables and checkpatch.pl complains about them: WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gc_seq; WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt + volatile int gced_lnum; Well, we anyway use smp_wmb() for c->gc_seq and c->gced_lnum, so these 'volatile' modifiers can be just dropped.

2008-12-31UBIFS: simplify make_free_spaceArtem Bityutskiy1-102/+49
The 'make_free_space()' function was too complex and this patch simplifies it. It also fixes a bug - the freespace test failed straight away on UBI volumes with 512 bytes LEB size. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: do not lie about used blocksArtem Bityutskiy1-10/+0
Do not force UBIFS return 0 used space when it is empty. It leads to a situation when creating any file immediately produces tens of used blocks, which looks very weird. It is better to be honest and say that some blocks are used even if the FS is empty. And ext2 does the same. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: restore budg_uncommitted_idxArtem Bityutskiy1-3/+12
UBIFS stores uncommitted index size in c->budg_uncommitted_idx, and this affect budgeting calculations. When mounting and replaying, this variable is not updated, so we may end up with "over-budgeting". This patch fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: always commit on unmountArtem Bityutskiy1-11/+15
UBIFS commits on unmount to make the next mount faster. Currently, it commits only if there is more than LEB size bytes in the journal. This is not very good, because journal size may be large (512KiB). And there may be few deletions in the journal which do not take much journal space, but which do introduce a lot of TNC changes and make mount slow. Thus, jurt remove this condition and always commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: use ubi_syncArtem Bityutskiy1-6/+1

2008-12-31UBIFS: always commit in sync_fsArtem Bityutskiy1-20/+18
Always run commit in sync_fs, because even if the journal seems to be almost empty, there may be a deletion which removes a large file, which affects the index greatly. And because we want better free space predictions after 'sync_fs()', we have to commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix file-system synchronizationArtem Bityutskiy1-0/+18
Argh. The ->sync_fs call is called _before_ all inodes are flushed. This means we first sync write buffers and commit, then all inodes are synced, and we end up with unflushed write buffers! Fix this by forcing synching all indoes from 'ubifs_sync_fs()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix constants initializationArtem Bityutskiy1-5/+20
The c->min_idx_lebs constant depends on c->old_idx_sz, which is read from the master node. This means that we have to initialize c->min_idx_lebs only after we have read the master node. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-12-23UBIFS: re-calculate min_idx_size after the commitArtem Bityutskiy1-0/+2
When we commit, but before we try to write anything to the flash media, @c->min_idx_size is inaccurate, because we do not re-calculate it after the commit. Do not forget to do this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-12-03UBIFS: slight compression optimizationArtem Bityutskiy2-3/+10

2008-11-21UBIFS: pre-allocate bulk-read bufferArtem Bityutskiy3-18/+76
To avoid memory allocation failure during bulk-read, pre-allocate a bulk-read buffer, so that if there is only one bulk-reader at a time, it would just use the pre-allocated buffer and would not do any memory allocation. However, if there are more than 1 bulk- reader, then only one reader would use the pre-allocated buffer, while the other reader would allocate the buffer for itself. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-11-21UBIFS: do not allocate too muchArtem Bityutskiy4-33/+60
Bulk-read allocates 128KiB or more using kmalloc. The allocation starts failing often when the memory gets fragmented. UBIFS still works fine in this case, because it falls-back to standard (non-optimized) read method, though. This patch teaches bulk-read to allocate exactly the amount of memory it needs, instead of allocating 128KiB every time. This patch is also a preparation to the further fix where we'll have a pre-allocated bulk-read buffer as well. For example, now the @bu object is prepared in 'ubifs_bulk_read()', so we could path either pre-allocated or allocated information to 'ubifs_do_bulk_read()' later. Or teaching 'ubifs_do_bulk_read()' not to allocate 'bu->buf' if it is already there. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-11-21UBIFS: do not print scary memory allocation warningsArtem Bityutskiy3-8/+15
Bulk-read allocates a lot of memory with 'kmalloc()', and when it is/gets fragmented 'kmalloc()' fails with a scarry warning. But because bulk-read is just an optimization, UBIFS keeps working fine. Supress the warning by passing __GFP_NOWARN option to 'kmalloc()'. This patch also introduces a macro for the magic 128KiB constant. This is just neater. Note, this is not really fixes the problem we had, but just hides the warnings. The further patches fix the problem. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-11-14CRED: Wrap task credential accesses in the UBIFS filesystemDavid Howells2-3/+3
Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

2008-11-07UBIFS: allow for gaps when dirtying the LPTAdrian Hunter1-2/+0
The LPT may have gaps in it because initially empty LEBs are not added by mkfs.ubifs - because it does not know how many there are. Then UBIFS allocates empty LEBs in the reverse order that they are discovered i.e. they are added to, and removed from, the front of a list. That creates a gap in the middle of the LPT. The function dirtying the LPT tree (for the purpose of small model garbage collection) assumed that a gap could only occur at the very end of the LPT and stopped dirtying prematurely, which in turn resulted in the LPT running out of space - something that is designed to be impossible.

Noticed by sparse: fs/ubifs/file.c:75:2: warning: restricted __le64 degrades to integer fs/ubifs/file.c:629:4: warning: restricted __le64 degrades to integer fs/ubifs/dir.c:431:3: warning: restricted __le64 degrades to integer This should be checked to ensure the ubifs_assert is working as intended, I've done the suggested annotation in this patch. fs/ubifs/sb.c:298:6: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:298:6: expected int [signed] [assigned] tmp fs/ubifs/sb.c:298:6: got restricted __le64 [usertype] <noident> fs/ubifs/sb.c:299:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:299:19: expected restricted __le64 [usertype] atime_sec fs/ubifs/sb.c:299:19: got int [signed] [assigned] tmp fs/ubifs/sb.c:300:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:300:19: expected restricted __le64 [usertype] ctime_sec fs/ubifs/sb.c:300:19: got int [signed] [assigned] tmp fs/ubifs/sb.c:301:19: warning: incorrect type in assignment (different base types) fs/ubifs/sb.c:301:19: expected restricted __le64 [usertype] mtime_sec fs/ubifs/sb.c:301:19: got int [signed] [assigned] tmp This looks like a bugfix as your tmp was a u32 so there was truncation in the atime, mtime, ctime value, probably not intentional, add a tmp_le64 and use it here. fs/ubifs/key.h:348:9: warning: cast to restricted __le32 fs/ubifs/key.h:348:9: warning: cast to restricted __le32 fs/ubifs/key.h:419:9: warning: cast to restricted __le32 Read from the annotated union member instead. fs/ubifs/recovery.c:175:13: warning: incorrect type in assignment (different base types) fs/ubifs/recovery.c:175:13: expected unsigned int [unsigned] [usertype] save_flags fs/ubifs/recovery.c:175:13: got restricted __le32 [usertype] flags fs/ubifs/recovery.c:186:13: warning: incorrect type in assignment (different base types) fs/ubifs/recovery.c:186:13: expected restricted __le32 [usertype] flags fs/ubifs/recovery.c:186:13: got unsigned int [unsigned] [usertype] save_flags Do byteshifting at compile time of the flag value.

2008-11-06UBIFS: remove printkArtem Bityutskiy1-2/+2
Remove the "UBIFS background thread ubifs_bgd0_0 started" message. We kill the background thread when we switch to R/O mode, and start it again whan we switch to R/W mode. OLPC is doing this many times during boot, and we see this message many times as well, which is irritating. So just kill the message. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-10-19UBIFS: amend printkArtem Bityutskiy1-1/+1
It is better to print "Reserved for root" than "Reserved pool size", because it is more obvious for users what this means. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
