2014-06-06fs/affs: pr_debug cleanupFabian Frederick1-16/+23
- Remove AFFS: prefix (defined in pr_fmt) - Use __func__ - Separate format/arguments on lines > 80 characters. Signed-off-by: Fabian Frederick <fabf@skynet.be> Cc: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-04-07affs: add mount option to avoid filename truncatesFabian Frederick1-9/+23
Normal behavior for filenames exceeding specific filesystem limits is to refuse operation. AFFS standard name length being only 30 characters against 255 for usual Linux filesystems, original implementation does filename truncate by default with a define value AFFS_NO_TRUNCATE which can be enabled but needs module compilation. This patch adds 'nofilenametruncate' mount option so that user can easily activate that feature and avoid a lot of problems (eg overwrite files ...)

2013-06-29Don't pass inode to ->d_hash() and ->d_compare()Linus Torvalds1-18/+8
Instances either don't look at it at all (the majority of cases) or only want it to find the superblock (which can be had as dentry->d_sb). A few cases that want more are actually safe with dentry->d_inode - the only precaution needed is the check that it hadn't been replaced with NULL by rmdir() or by overwriting rename(), which case should be simply treated as cache miss.

2012-07-14don't pass nameidata to ->create()Al Viro1-1/+1
boolean "does it have to be exclusive?" flag is passed instead; Local filesystem should just ignore it - the object is guaranteed not to be there yet. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-07-14stop passing nameidata to ->lookup()Al Viro1-1/+1
Just the flags; only NFS cares even about that, but there are legitimate uses for such argument. And getting rid of that completely would require splitting ->lookup() into a couple of methods (at least), so let's leave that alone for now... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-01-03switch ->create() to umode_tAl Viro1-2/+2
vfs_create() ignores everything outside of 16bit subset of its mode argument; switching it to umode_t is obviously equivalent and it's the only caller of the method Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-01-03switch vfs_mkdir() and ->mkdir() to umode_tAl Viro1-2/+2
vfs_mkdir() gets int, but immediately drops everything that might not fit into umode_t and that's the only caller of ->mkdir()... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-11-02filesystems: add missing nlink wrappersMiklos Szeredi1-3/+3
Replace direct i_nlink updates with the respective updater function (inc_nlink, drop_nlink, clear_nlink, inode_dec_link_count). Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
2011-05-28affs: remove unnecessary dentry_unhash on rmdir, dir renameSage Weil1-5/+0

2011-05-26vfs: push dentry_unhash on rename_dir into file systemsSage Weil1-0/+3
Only a few file systems need this. Start by pushing it down into each rename method (except gfs2 and xfs) so that it can be dealt with on a per-fs basis. Acked-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Sage Weil <sage@newdream.net> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Only a few file systems need this. Start by pushing it down into each fs rmdir method (except gfs2 and xfs) so it can be dealt with on a per-fs basis.

2011-01-07fs: dcache reduce branches in lookup pathNick Piggin1-1/+1
Reduce some branches and memory accesses in dcache lookup by adding dentry flags to indicate common d_ops are set, rather than having to check them. This saves a pointer memory access (dentry->d_op) in common path lookup situations, and saves another pointer load and branch in cases where we have d_op but not the particular operation. Patched with: git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-07fs: change d_hash for rcu-walkNick Piggin1-8/+12
Change d_hash so it may be called from lock-free RCU lookups. See similar patch for d_compare for details. For in-tree filesystems, this is just a mechanical change. Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-07fs: change d_compare for rcu-walkNick Piggin1-18/+28
Change d_compare so it may be called from lock-free RCU lookups. This does put significant restrictions on what may be done from the callback, however there don't seem to have been any problems with in-tree fses. If some strange use case pops up that _really_ cannot cope with the rcu-walk rules, we can just add new rcu-unaware callbacks, which would cause name lookup to drop out of rcu-walk mode. For in-tree filesystems, this is just a mechanical change. Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2010-05-27fs/affs: use ERR_CASTJulia Lawall1-1/+1
Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more clear what is the purpose of the operation, which otherwise looks like a no-op. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ type T; T x; identifier f; @@ T f (...) { <+... - ERR_PTR(PTR_ERR(x)) + x ...+> } @@ expression x; @@ - ERR_PTR(PTR_ERR(x)) + ERR_CAST(x) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-06[PATCH] fix reservation discarding in affsRoman Zippel1-2/+4
- remove affs_put_inode, so preallocations aren't discared unnecessarily often. - remove affs_drop_inode, it's called with a spinlock held, so it can't use a mutex. - make i_opencnt atomic - avoid direct b_count manipulations - a few allocation failure fixes, so that these are more gracefully handled now.

2008-02-07iget: stop AFFS from using iget() and read_inode()David Howells1-6/+4
Stop the AFFS filesystem from using iget() and read_inode(). Replace affs_read_inode() with affs_iget(), and call that instead of iget(). affs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. affs_fill_super() returns any error incurred when getting the root inode instead of EINVAL.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+443
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
