fs: rename inode_lock to inode_hash_lock

2011-03-25T01:17:51+00:00

All that remains of the inode_lock is protecting the inode hash list
manipulation and traversals. Rename the inode_lock to
inode_hash_lock to reflect it's actual function.

fsnotify: implement ordering between notifiers

2010-10-28T21:22:13+00:00

fanotify needs to be able to specify that some groups get events before
others.  They use this idea to make sure that a hierarchical storage
manager gets access to files before programs which actually use them.  This
is purely infrastructure.  Everything will have a priority of 0, but the
infrastructure will exist for it to be non-zero.

fsnotify: use an explicit flag to indicate fsnotify_destroy_mark has been called

2010-07-28T14:18:52+00:00

Currently fsnotify check is mark->group is NULL to decide if
fsnotify_destroy_mark() has already been called or not.  With the upcoming
rcu work it is a heck of a lot easier to use an explicit flag than worry
about group being set to NULL.

fsnotify: use _rcu functions for mark list traversal

2010-07-28T14:18:51+00:00

In preparation for srcu locking use all _rcu appropiete functions for mark
list addition, removal, and traversal.  The operations are still done under a
spinlock at the end of this patch.

fsnotify: place marks on object in order of group memory address

2010-07-28T14:18:51+00:00

fsnotify_marks currently are placed on objects (inodes or vfsmounts) in
arbitrary order.  This patch places them in order of the group memory address.

fsnotify: update gfp/slab.h includes

2010-07-28T13:59:03+00:00

Implicit slab.h inclusion via percpu.h is about to go away.  Make sure
gfp.h or slab.h is included as necessary.

fanotify: clear all fanotify marks

2010-07-28T13:59:00+00:00

fanotify listeners may want to clear all marks.  They may want to do this
to destroy all of their inode marks which have nothing but ignores.
Realistically this is useful for av vendors who update policy and want to
clear all of their cached allows.

fsnotify: vfsmount marks generic functions

2010-07-28T13:58:57+00:00

Much like inode-mark.c has all of the code dealing with marks on inodes
this patch adds a vfsmount-mark.c which has similar code but is intended
for marks on vfsmounts.
