From e0c9c0afd2fc958ffa34b697972721d81df8a56f Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 1 Apr 2015 18:30:06 -0500 Subject: [PATCH] mnt: Update detach_mounts to leave mounts connected Now that it is possible to lazily unmount an entire mount tree and leave the individual mounts connected to each other add a new flag UMOUNT_CONNECTED to umount_tree to force this behavior and use this flag in detach_mounts. This closes a bug where the deletion of a file or directory could trigger an unmount and reveal data under a mount point. Cc: stable@vger.kernel.org Signed-off-by: "Eric W.
