The first is a fix for a race that can causes oopses under the right circumstances, and that someone just recently encountered. 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. I have dropped the mount hash table fix that Al objected to and will come back to that when the discussion around that patch is complete. Andrei Vagin (1): pid: fix lockdep deadlock warning due to ucount_lock Eric W. Biederman (2): mnt: Protect the mountpoint hashtable with mount_lock 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/namespace.c | 64 +++++++++++++++++++++++++++++++++++--------------- fs/proc/proc_sysctl.c | 3 ++- kernel/pid_namespace.c | 10 ++++---- 5 files changed, 60 insertions(+), 27 deletions(-) Eric
