GFS2: Pull request (merge window) addendum

[Bob Peterson]

Hi Linus,

Please consider pulling the following additional patch for the GFS2 file system.

Sorry for the lack of bake time on this one, but it is high priority, simple, and has been well tested.

  gfs2: Add missing rcu locking for glock	lookup (2017-02-23 10:06:00 -0500)

----------------------------------------------------------------
This is an addendum for the 4.11 merge window.

Andy Price wrote this patch to close a nasty race condition
that allows access to glocks that are being destroyed. Without
this patch, GFS2 is vulnerable to random corruption and kernel
panic.
