From 98ab494dd1d25388981114057cf9446250cc7dc7 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 17 Jun 2011 09:32:10 -0400 Subject: cifs: move cifs_umount() call into ->kill_sb() instead of calling it manually in case if cifs_read_super() fails to set ->s_root, just call it from ->kill_sb(). cifs_put_super() is gone now *and* we have cifs_sb shutdown and destruction done after the superblock is gone from ->s_instances.
