ext2: Remove s_dirt handling

2012-04-11T09:12:45+00:00

Places which modify superblock feature / state fields mark the superblock buffer dirty so it is written out by flusher thread. Thus there's no need to set s_dirt there. The only other fields changing in the superblock are the numbers of free blocks, free inodes and s_wtime. There's no real need to write (or even compute) these periodically. Free blocks / inodes counters are recomputed on every mount from group counters anyway and value of s_wtime is only informational and imprecise anyway. So it should be enough to write these opportunistically on mount, remount, umount, and sync_fs times. Signed-off-by: Jan Kara

ext2/3/4: delete unneeded includes of module.h

2012-01-09T12:52:10+00:00

Delete any instances of include module.h that were not strictly required. In the case of ext2, the declaration of MODULE_LICENSE etc. were in inode.c but the module_init/exit were in super.c, so relocate the MODULE_LICENCE/AUTHOR block to super.c which makes it consistent with ext3 and ext4 at the same time.

ext2: check xattr name_len before acquiring xattr_sem in ext2_xattr_get

2011-07-22T17:41:16+00:00

In ext2_xattr_get(), the code will acquire xattr_sem first, later checks the length of xattr name_len > 255. It's unnecessarily time consuming and also ext2_xattr_set() checks the length before other checks. So move the check before acquiring xattr_sem to make these two functions consistent.

fs: add sync_inode_metadata

2010-10-26T01:18:19+00:00

Add a new helper to write out the inode using the writeback code, that is including the correct dirty bit and list manipulation. A few of filesystems already opencode this, and a lot of others should be using it instead of using write_inode_now which also writes out the data.

mbcache: Remove unused features

2010-08-09T20:48:45+00:00

The mbcache code was written to support a variable number of indexes, but all the existing users use exactly one index. Simplify to code to support only that case. There are also no users of the cache entry free operation, and none of the users keep extra data in cache entries. Remove those features as well.
