fanotify: use __aligned_u64 in fanotify userspace metadata
Currently the userspace struct exposed by fanotify uses __attribute__((packed)) to make sure that alignment works on multiarch platforms. Since this causes a severe performance penalty on some platforms we are going to switch to using explicit alignment notation on the 64bit values so we don't have to use 'packed' Signed-off-by: Eric Paris <eparis@redhat.com>
