[GIT PULL] gfs2 changes

[Andreas Gruenbacher]

Dear Linus,

please consider pulling the following gfs2 fixes and cleanups:

* The first 15 of these patches rework the glock refcounting and LRU list
  handling to be more sensible.

* The following 13 patches clean up the quota code, add some missing locking,
  and work around the on-disk corruption that the reverted patch "gfs2: ignore
  negated quota changes" causes.

* The final patch cleans up the glock demote logic in glock_work_func().

Thanks,
Andreas
