2011-01-07	fs: dcache reduce branches in lookup path	Nick Piggin	1	-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>
2011-01-07	fs: change d_hash for rcu-walk	Nick Piggin	1	-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>
2011-01-07	fs: change d_compare for rcu-walk	Nick Piggin	1	-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>
2010-05-27	fs/affs: use ERR_CAST	Julia Lawall	1	-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>
2010-01-26	Fix remount races with symlink handling in affs	Al Viro	1	-2/+5
	A couple of fields in affs_sb_info is used in follow_link() and symlink() for handling AFFS "absolute" symlinks. Need locking against affs_remount() updates. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-05-06	[PATCH] fix reservation discarding in affs	Roman Zippel	1	-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.

2008-02-07	iget: stop AFFS from using iget() and read_inode()	David Howells	1	-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.

2008-02-07	Convert ERR_PTR(PTR_ERR(p)) instances to ERR_CAST(p)	David Howells	1	-1/+1
	Convert instances of ERR_PTR(PTR_ERR(p)) to ERR_CAST(p) using: perl -spi -e 's/ERR_PTR[(]PTR_ERR[(](.)[)][)]/ERR_CAST(\1)/' `grep -rl 'ERR_PTR[(]PTR_ERR' fs crypto net security` Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2006-05-26	[PATCH] affs: possible null pointer dereference in affs_rename()	Florin Malita	1	-2/+1
	If affs_bread() fails, the exit path calls mark_buffer_dirty_inode() with a NULL argument. Coverity CID: 312. Signed-off-by: Florin Malita <fmalita@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-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!
