filesystem notification: create fs/notify to contain all fs notification · 272eb014

由 Eric Paris 提交于 12月 17, 2008

Creating a generic filesystem notification interface, fsnotify, which will be
used by inotify, dnotify, and eventually fanotify is really starting to
clutter the fs directory.  This patch simply moves inotify and dnotify into
fs/notify/inotify and fs/notify/dnotify respectively to make both current fs/
and future notification tidier.

fs/block_dev.c: __read_mostly improvement and sb_is_blkdev_sb utilization · c2acf7b9

由 Denis ChengRq 提交于 12月 01, 2008

- iget5_locked in bdget really needs blockdev_superblock, instead of
  bd_mnt, so bd_mnt could be just a local variable;

- blockdev_superblock really needs __read_mostly, while local var bd_mnt
  not;

- make use of sb_is_blkdev_sb in bd_forget, instead of direct reference
  to blockdev_superblock.

kill ->dir_notify() · 6badd79b

由 Al Viro 提交于 12月 26, 2008

Remove the hopelessly misguided ->dir_notify(). The only instance (cifs)
has been broken by design from the very beginning; the objects it creates
are never destroyed, keep references to struct file they can outlive, nothing
that could possibly evict them exists on close(2) path *and* no locking
whatsoever is done to prevent races with close(), should the previous, er,
deficiencies someday be dealt with.

filp_cachep can be static in fs/file_table.c · b6b3fdea

由 Eric Dumazet 提交于 12月 10, 2008

Instead of creating the "filp" kmem_cache in vfs_caches_init(),
we can do it a litle be later in files_init(), so that filp_cachep
is static to fs/file_table.c

fix f_count description in Documentation/filesystems/files.txt · fd659fd6

f_count became an atomic_long_t.

由 Steven Rostedt 提交于 12月 10, 2008

[AV: rediffed on top of unification of init_fs]
Initialization of init_fs still uses the deprecated RW_LOCK_UNLOCKED macro.
This patch updates it to use the __RW_LOCK_UNLOCKED(lock) macro.

kill vfs_permission · cb23beb5

由 Christoph Hellwig 提交于 10月 24, 2008

With all the nameidata removal there's no point anymore for this helper.
Of the three callers left two will go away with the next lookup series
anyway.

Also add proper kerneldoc to inode_permission as this is the main
permission check routine now.

Explain that you really need to use the return value of d_path rather than
the buffer you passed into it.

Also fix the comment for seq_path(), the function arguments changed
recently but the comment hadn't been updated in sync.
