Superblock lock was replaced with (un)lock_super() removal, but left uninitialized for Seventh Edition UNIX filesystem in the following commit (3.7): c07cb01 sysv: drop lock/unlock super Signed-off-by: Lubomir Rintel <lkundrak@xxxxx> Signed-off-by: Christoph Hellwig <hch@xxxxxx> Signed-off-by: Al Viro <viro@xxxxxxxxxxxxxxxxxx> --- This is a simple oneliner fix to an oops (resulting in the mount hang) when a v7 filesystem is mounted. Please apply to whichever stable trees that are currently maintained.
