This patch series implements fsnotify a filesystem notification backend which
should be the basis for dnotify, inotify, and eventually fanotify.
This series only reimplements dnotify using the new fsnotify backend. If
accepted I will do the work to port inotify as well. Currently struct inode
goes from:
#ifdef CONFIG_DNOTIFY
unsigned long i_dnotify_mask; /* Directory notify events */
struct dnotify_struct *i_dnotify; /* for directory notifications */
#endif
to:
#ifdef CONFIG_FSNOTIFY
unsigned long i_fsnotify_mask; /* all events this inode cares about */
struct list_head i_fsnotify_mark_entries; /* fsnotify mark entries */
spinlock_t i_fsnotify_lock; /* protect the entries list */
#endif
so the inode still grows, but the inotify fields will be dropped as well
resulting in a smaller struct inode. These are all the fields fanotify will
want as well.
rwlocks have been completely dropped in favor of even smaller critical section
spinlocks. i_lock is no longer used to protect dnotify information and
instead the more specific i_fsnotify_lock is used.

Eric Paris (8):
dnotify: reimplement dnotify using fsnotify
fsnotify: add in inode fsnotify markings
fsnotify: add group priorities
fsnotify: unified filesystem notification backend
fsnotify: use the new open-exec hook for inotify and dnotify
fsnotify: sys_execve and sys_uselib do not call into fsnotify
fsnotify: pass a file instead of an inode to open, read, and write
filesystem notification: create fs/notify to contain all fs notification
