Subject: [PATCH 07/20] fanotify: allow userspace to flush all marks

fanotify is supposed to be able to flush all marks.  This is mostly useful
for the AV community to flush all cached decisions on a security policy
change.  This functionality has existed in the kernel but wasn't correctly
exposed to userspace.
