Subject[PATCH 2/3] vfs: O_* bit numbers uniqueness check fix
Follow the comment by Eric:

Until the FMODE_ and O_ bits do not overload I think we need to check
FMODE_EXEC and FMODE_NONOTIFY (if you have that one) inside fcntl_init()
as well. I guess I'll send a patch to someone ?Al? to add FMODE_EXEC to
the list....
