fanotify: fscking all notification system fanotify is a novel file notification system which bases notification on giving userspace both an event type (open, close, read, write) and an open file descriptor to the object in question. This should address a number of races and problems with other notification systems like inotify and dnotify and should allow the future implementation of blocking or access controlled notification. These are useful for on access scanners or hierachical storage management schemes. This patch just implements the basics of the fsnotify functions. Signed-off-by: Eric Paris <eparis@redhat.com>

config FANOTIFY
bool "Filesystem wide access notification"
select FSNOTIFY
fanotify: select ANON_INODES. fanotify references anon_inode_getfd(), which is only available with ANON_INODES enabled. Presently this bails out with the following: LD vmlinux fs/built-in.o: In function `sys_fanotify_init': (.text+0x26d1c): undefined reference to `anon_inode_getfd' make: *** [vmlinux] Error 1 which is trivially corrected by adding an ANON_INODES select.

default y
---help---
Say Y here to enable fanotify suport. fanotify is a file access
notification system which differs from inotify in that it sends
and open file descriptor to the userspace listener along with
the event.
If unsure, say Y.
