  GFS2: Minor improvements to comments and documentation (2018-04-12 10:07:51 -0700)

----------------------------------------------------------------
We decided to request the latest three patches to be merged into this
merge window while it's still open.

1. The first patch adds a new function to lockref: lockref_put_not_zero
2. The second patch fixes GFS2's glock dump code so it uses the new lockref
   function. This fixes a problem whereby lock dumps could miss glocks.
3. I made a minor patch to update some comments and fix the lock ordering
   text in our gfs2-glocks.txt Documentation file.
