CPT: relax check for several bind mounts on the same mount point Relax check for special bind mounts which mounted several times on the same mount point. We need to check only dentry, mount check can be skipped in this case. We can't remove completely mount check as there are exist cases when we need to check mnt too. E.g. /dev is mounted with NODEV over /dev and some file is opened from underlying mount. If mount check is removed, then we will be able to checkpoint such state, but we will not be able to restore it. Correct sollution will be to dump/restore whole mount tree with overmounts. But we can't implement this right now for number of reasons. Bug #84310 Signed-off-by: Pavel Emelyanov <xemul@openvz.org>
