[CPT] namespace semaphore possible deadlock Old bug. To my shame I knew about this, but ignored. The fix is to drop namespace semaphore. We make mntget() on current mnt, so that it will not disappear from under us. It still can be unmounted with MNT_DETACH, in this case we cannot proceed with scanning mnt list and we must not: unmounting something inside VE while checkpointing is an obvious good reason to fail.
