-From: Vasily Averin <vvs@openvz.org>
-Subject: [PATCH v4] fs: umount on symlink leaks mnt count
-Currently umount on symlink blocks following umount:
-
-/vz is separate mount
-
-# ls /vz/ -al | grep test
-drwxr-xr-x. 2 root root 4096 Jul 19 01:14 testdir
-lrwxrwxrwx. 1 root root 11 Jul 19 01:16 testlink -> /vz/testdir
-# umount -l /vz/testlink
-umount: /vz/testlink: not mounted (expected)
-# lsof /vz
-# umount /vz
-umount: /vz: device is busy. (unexpected)
-
-In this case mountpoint_last() gets an extra refcount on path->mnt
