linux.git/fs/namespace.c, branch v2.6.28 Linux kernel source tree vfs: fix shrink_submounts 2008-11-13T01:17:17+00:00 Eric W. Biederman ebiederm@xmission.com 2008-11-12T21:26:54+00:00 afef80b3d87cae574b8c6b763505f25b74d254ef In the last refactoring of shrink_submounts a variable was not completely renamed. So finish the renaming of mnt to m now. Without this if you attempt to mount an nfs mount that has both automatic nfs sub mounts on it, and has normal mounts on it. The unmount will succeed when it should not. Signed-off-by: Eric W.
