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>

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.

Say Y here is you want fanotify listeners to be able to make permissions
decisions concerning filesystem events. This is used by some fanotify
listeners which need to scan files before allowing the system access to
use those files. This is used by some anti-malware vendors and by some
hierarchical storage managent systems.
If unsure, say N.
