From 5d88457eb5b86b475422dc882f089203faaeedb5 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 3 Jan 2015 05:39:35 -0600 Subject: [PATCH] mnt: On an unmount propagate clearing of MNT_LOCKED A prerequisite of calling umount_tree is that the point where the tree is mounted at is valid to unmount. If we are propagating the effect of the unmount clear MNT_LOCKED in every instance where the same filesystem is mounted on the same mountpoint in the mount tree, as we know (by virtue of the fact that umount_tree was called) that it is safe to reveal what is at that mountpoint.
