fsnotify: use def_bool in kconfig instead of letting the user choose

2009-07-21T19:26:26+00:00

fsnotify doens't give the user anything.  If someone chooses inotify or
dnotify it should build fsnotify, if they don't select one it shouldn't be
built.  This patch changes fsnotify to be a def_bool=n and makes everything
else select it.  Also fixes the issue people complained about on lwn where
gdm hung because they didn't have inotify and they didn't get the inotify
build option.....

fsnotify: allow groups to set freeing_mark to null

2009-06-11T18:57:55+00:00

Most fsnotify listeners (all but inotify) do not care about marks being
freed.  Allow groups to set freeing_mark to null and do not call any
function if it is set that way.

inotify/dnotify: should_send_event shouldn't match on FS_EVENT_ON_CHILD

2009-06-11T18:57:54+00:00

inotify and dnotify will both indicate that they want any event which came
from a child inode.  The fix is to mask off FS_EVENT_ON_CHILD when deciding
if inotify or dnotify is interested in a given event.

dnotify: do not bother to lock entry->lock when reading mask

2009-06-11T18:57:54+00:00

entry->lock is needed to make sure entry->mask does not change while
manipulating it.  In dnotify_should_send_event() we don't care if we get an
old or a new mask value out of this entry so there is no point it taking
the lock.

dnotify: do not use ?true:false when assigning to a bool

2009-06-11T18:57:54+00:00

dnotify_should send event assigned a bool using ?true:false when computing
a bit operation.  This is poitless and the bool type does this for us.

fsnotify: allow groups to add private data to events

2009-06-11T18:57:54+00:00

inotify needs per group information attached to events.  This patch allows
groups to attach private information and implements a callback so that
information can be freed when an event is being destroyed.

filesystem notification: create fs/notify to contain all fs notification

2008-12-31T23:07:43+00:00

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.
