2012-10-01Btrfs: turbo charge fsyncJosef Bacik8-42/+416
At least for the vm workload. Currently on fsync we will 1) Truncate all items in the log tree for the given inode if they exist and 2) Copy all items for a given inode into the log The problem with this is that for things like VMs you can have lots of extents from the fragmented writing behavior, and worst yet you may have only modified a few extents, not the entire thing. This patch fixes this problem by tracking which transid modified our extent, and then when we do the tree logging we find all of the extents we've modified in our current transaction, sort them and commit them. We also only truncate up to the xattrs of the inode and copy that stuff in normally, and then just drop any extents in the range we have that exist in the log already. Here are some numbers of a 50 meg fio job that does random writes and fsync()s after every write Original Patched SATA drive 82KB/s 140KB/s Fusion drive 431KB/s 2532KB/s So around 2-6 times faster depending on your hardware. There are a few corner cases, for example if you truncate at all we have to do it the old way since there is no way to be sure what is in the log is ok. This probably could be done smarter, but if you write-fsync-truncate-write-fsync you deserve what you get. All this work is in RAM of course so if your inode gets evicted from cache and you read it in and fsync it we'll do it the slow way if we are still in the same transaction that we last modified the inode in. The biggest cool part of this is that it requires no changes to the recovery code, so if you fsync with this patch and crash and load an old kernel, it will run the recovery and be a-ok. I have tested this pretty thoroughly with an fsync tester and everything comes back fine, as well as xfstests. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
2012-10-01Btrfs: fix possible corruption when fsyncing written prealloced extentsJosef Bacik1-0/+12
While working on my fsync patch my fsync tester kept hitting mismatching md5sums when I would randomly write to a prealloc'ed region, syncfs() and then write to the prealloced region some more and then fsync() and then immediately reboot. This is because the tree logging code will skip writing csums for file extents who's generation is less than the current running transaction. When we mark extents as written we haven't been updating their generation so they were always being skipped. This wouldn't happen if you were to preallocate and then write in the same transaction, but if you for example prealloced a VM you could definitely run into this problem. This patch makes my fsync tester happy again. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
2012-10-01Btrfs: do not allocate chunks as agressivelyJosef Bacik1-9/+3
Swinging this pendulum back the other way. We've been allocating chunks up to 2% of the disk no matter how much we actually have allocated. So instead fix this calculation to only allocate chunks if we have more than 80% of the space available allocated. Please test this as it will likely cause all sorts of ENOSPC problems to pop up suddenly. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
2012-10-01Btrfs: update last trans if we don't update the inodeJosef Bacik1-0/+2
There is a completely impossible situation to hit where you can preallocate a file, fsync it, write into the preallocated region, have the transaction commit twice and then fsync and then immediately lose power and lose all of the contents of the write. This patch fixes this just so I feel better about the situation and because it is lightweight, we just update the last_trans when we finish an ordered IO and we don't update the inode itself. This way we are completely safe and I feel better. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

2012-10-01Btrfs: fix btrfs send for inline items and compressionChris Mason3-15/+37
The btrfs send code was assuming the offset of the file item into the extent translated to bytes on disk. If we're compressed, this isn't true, and so it was off into extents owned by other files. It was also improperly handling inline extents. This solves a crash where we may have gone past the end of the file extent item by not testing early enough for an inline extent. It also solves problems where we have a whole between the end of the inline item and the start of the full extent. Signed-off-by: Chris Mason <chris.mason@fusionio.com>

2012-09-29vfs: dcache: fix deadlock in tree traversalMiklos Szeredi1-0/+6
IBM reported a deadlock in select_parent(). This was found to be caused by taking rename_lock when already locked when restarting the tree traversal. There are two cases when the traversal needs to be restarted: 1) concurrent d_move(); this can only happen when not already locked, since taking rename_lock protects against concurrent d_move(). 2) racing with final d_put() on child just at the moment of ascending to parent; rename_lock doesn't protect against this rare race, so it can happen when already locked. Because of case 2, we need to be able to handle restarting the traversal when rename_lock is already held. This patch fixes all three callers of try_to_ascend(). IBM reported that the deadlock is gone with this patch.

2012-09-28mtdchar: fix offset overflow detectionLinus Torvalds1-6/+42
Sasha Levin has been running trinity in a KVM tools guest, and was able to trigger the BUG_ON() at arch/x86/mm/pat.c:279 (verifying the range of the memory type). The call trace showed that it was mtdchar_mmap() that created an invalid remap_pfn_range(). The problem is that mtdchar_mmap() does various really odd and subtle things with the vma page offset etc, and uses the wrong types (and the wrong overflow) detection for it. For example, the page offset may well be 32-bit on a 32-bit architecture, but after shifting it up by PAGE_SHIFT, we need to use a potentially 64-bit resource_size_t to correctly hold the full value. Also, we need to check that the vma length plus offset doesn't overflow before we check that it is smaller than the length of the mtdmap region. This fixes things up and tries to make the code a bit easier to read.

2012-09-27bnx2: Clean up remaining iounmapNeil Horman1-1/+1
commit c0357e975afdbbedab5c662d19bef865f02adc17 modified bnx2 to switch from using ioremap/iounmap to pci_iomap/pci_iounmap. They missed a spot in the error path of bnx2_init_one though. This patch just cleans that up. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Michael Chan <mcan@broadcom.com> CC: "David S.
