Revert "fsnotify: store struct file not struct path"

2010-08-12T21:23:04+00:00

This reverts commit 3bcf3860a4ff9bbc522820b4b765e65e4deceb3e (and the
accompanying commit c1e5c954020e "vfs/fsnotify: fsnotify_close can delay
the final work in fput" that was a horribly ugly hack to make it work at
all).

The 'struct file' approach not only causes that disgusting hack, it
somehow breaks pulseaudio, probably due to some other subtlety with
f_count handling.

Fix up various conflicts due to later fsnotify work.

fanotify: use both marks when possible

2010-07-28T14:18:55+00:00

fanotify currently, when given a vfsmount_mark will look up (if it exists)
the corresponding inode mark.  This patch drops that lookup and uses the
mark provided.

fsnotify: pass both the vfsmount mark and inode mark

2010-07-28T14:18:54+00:00

should_send_event() and handle_event() will both need to look up the inode
event if they get a vfsmount event.  Lets just pass both at the same time
since we have them both after walking the lists in lockstep.

fsnotify: remove group->mask

2010-07-28T14:18:54+00:00

group->mask is now useless.  It was originally a shortcut for fsnotify to
save on performance.  These checks are now redundant, so we remove them.

fsnotify: cleanup should_send_event

2010-07-28T14:18:53+00:00

The change to use srcu and walk the object list rather than the global
fsnotify_group list means that should_send_event is no longer needed for a
number of groups and can be simplified for others.  Do that.

audit: use the mark in handler functions

2010-07-28T14:18:53+00:00

audit now gets a mark in the should_send_event and handle_event
functions.  Rather than look up the mark themselves audit should just use
the mark it was handed.

fsnotify: send fsnotify_mark to groups in event handling functions

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

With the change of fsnotify to use srcu walking the marks list instead of
walking the global groups list we now know the mark in question.  The code can
send the mark to the group's handling functions and the groups won't have to
find those marks themselves.

fsnotify: store struct file not struct path

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

Al explains that calling dentry_open() with a mnt/dentry pair is only
garunteed to be safe if they are already used in an open struct file.  To
make sure this is the case don't store and use a struct path in fsnotify,
always use a struct file.

fsnotify: split generic and inode specific mark code

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

currently all marking is done by functions in inode-mark.c.  Some of this
is pretty generic and should be instead done in a generic function and we
should only put the inode specific code in inode-mark.c

fsnotify: take inode->i_lock inside fsnotify_find_mark_entry()

2010-07-28T13:58:54+00:00

All callers to fsnotify_find_mark_entry() except one take and
release inode->i_lock around the call.  Take the lock inside
fsnotify_find_mark_entry() instead.
