affs: testing the wrong variable

2010-10-26T01:18:20Z

The intent was to verify that bh = affs_bread_ino(...) returned a valid pointer. We checked "ext_bh" earlier in the function and it's valid here. Signed-off-by: Dan Carpenter Signed-off-by: Al Viro

get rid of cont_write_begin_newtrunc

2010-08-09T20:47:31Z

Move the call to vmtruncate to get rid of accessive blocks to the callers in preparation of the new truncate sequence and rename the non-truncating version to cont_write_begin. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

sanitize ->fsync() for affs

2009-06-12T01:36:14Z

unfortunately, for affs (especially for affs directories) we have no real way to keep track of metadata ownership. So we have to do more or less what file_fsync() does, but we do *not* need to call write_super() there. Signed-off-by: Al Viro

fs: symlink write_begin allocation context fix

2009-01-04T21:33:20Z

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).

[PATCH] f_count may wrap around

2008-07-27T00:53:40Z

make it atomic_long_t; while we are at it, get rid of useless checks in affs, hfs and hpfs - ->open() always has it equal to 1, ->release() - to 0. Signed-off-by: Al Viro

[PATCH] fix reservation discarding in affs

2008-05-06T17:45:33Z

- 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.

fs/affs/file.c: use BUG_ON

2008-04-29T15:06:02Z

if (...) BUG(); should be replaced with BUG_ON(...) when the test has no side-effects to allow a definition of BUG_ON that drops the code completely. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @ disable unlikely @ expression E,f; @@ ( if (<... f(...) ...>) { BUG(); } | - if (unlikely(E)) { BUG(); } + BUG_ON(E); ) @@ expression E,f; @@ ( if (<... f(...) ...>) { BUG(); } | - if (E) { BUG(); } + BUG_ON(E); ) // Signed-off-by: Julia Lawall Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
