  "message": "sysfs: fix use-after-free in sysfs_kill_sb()\n\nWhile restructuring the [u]mount path, 4b93dc9b1c68 (\"sysfs, kernfs:\nprepare mount path for kernfs\") incorrectly updated sysfs_kill_sb() so\nthat it first kills super_block and then tries to dereference its\nnamespace tag to drop it.  Fix it by caching namespace tag before\nkilling the superblock and then drop the cached namespace tag.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Yuanhan Liu \u003cyuanhan.liu@linux.intel.com\u003e\nTested-by: Yuanhan Liu \u003cyuanhan.liu@linux.intel.com\u003e\nTested-by: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nLink: http://lkml.kernel.org/g/20131205031051.GC5135@yliu-dev.sh.intel.com\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n",
