From da01636a6511c3bd0c1cf546c47b8e92a837a613 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 8 Jan 2012 19:45:28 -0500 Subject: [PATCH] exofs: oops after late failure in mount We have already set ->s_root, so ->put_super() is going to be called. Freeing ->s_fs_info is a bloody bad idea when it's going to be dereferenced very shortly...
