fanotify: notify on mount attach and detach
Add notifications for attaching and detaching mounts. The following new
event masks are added:
FAN_MNT_ATTACH - Mount was attached
FAN_MNT_DETACH - Mount was detached
If a mount is moved, then the event is reported with (FAN_MNT_ATTACH |
FAN_MNT_DETACH).
These events add an info record of type FAN_EVENT_INFO_TYPE_MNT containing
these fields identifying the affected mounts:
__u64 mnt_id - the ID of the mount (see statmount(2))
FAN_REPORT_MNT must be supplied to fanotify_init() to receive these events
and no other type of event can be received with this report type.
Marks are added with FAN_MARK_MNTNS, which records the mount namespace from
an nsfs file (e.g. /proc/self/ns/mnt).
