By the commit
	ecf081d 2010-07-28 vfs: introduce FMODE_NONOTIFY
a new warning is produced.

In include/linux/fs.h
#define FMODE_NONOTIFY		((__force fmode_t)0x1000000)
	:::
#define OPEN_FMODE(flag) ((__force fmode_t)(((flag + 1) & O_ACCMODE) | \
					    (flag & FMODE_NONOTIFY)))

In fs/anon_inodes.c
anon_inode_getfile(..., int flags)
{
	file = alloc_file(&path, OPEN_FMODE(flags), fops);
}

Here the '&' operator handles the passed integer "flags" and "__force
fmode_t", and we get "warning: restricted fmode_t degrades to integer".

Can we stop this warning?
