Tejun Heo a7560a0132 sysfs: fix use-after-free in sysfs_kill_sb() ... While restructuring the [u]mount path, 4b93dc9b1c ("sysfs, kernfs: prepare mount path for kernfs") incorrectly updated sysfs_kill_sb() so that it first kills super_block and then tries to dereference its namespace tag to drop it. Fix it by caching namespace tag before killing the superblock and then drop the cached namespace tag.
