HEAD: cd293bfacd57928627ef7da6194e0cbe24db3291 sysctl: Drop reference added by grab_header in proc_sys_readdir
This tree contains 5 fixes.
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
