The first is a fix for a race that can causes oopses under the right circumstances, and that someone just recently encountered. The second is a fix that removes the possibility of creating unbounded chains in the mount hash table. After a lot of back and forth this fix has finally matured into something mergeable. Past that are several small trivial correct fixes. A real issue that was blocking development of an out of tree driver, but does not appear to have caused any actual problems for in-tree code. A potential deadlock that was reported by lockdep. And a deadlock people have experienced and took the time to track down caused by a cleanup that removed the code to drop a reference count. Andrei Vagin (1): pid: fix lockdep deadlock warning due to ucount_lock Eric W. Biederman (3): mnt: Protect the mountpoint hashtable with mount_lock mnt: Tuck mounts under others instead of creating shadow/side mounts. libfs: Modify mount_pseudo_xattr to be clear it is not a userspace mount Zhou Chengming (1): sysctl: Drop reference added by grab_header in proc_sys_readdir fs/dcache.c | 7 +- fs/libfs.c | 3 +- fs/mount.h | 1 - fs/namespace.c | 174 +++++++++++++++++++++++++++++-------------------- fs/pnode.c | 27 ++++++-- fs/pnode.h | 2 + fs/proc/proc_sysctl.c | 3 +- kernel/pid_namespace.c | 10 +-- 8 files changed, 142 insertions(+), 85 deletions(-) Eric
