Merge branch 'for-linus' of git://oss.sgi.com/xfs/xfs
Pull XFS updates from Ben Myers:
"Scalability improvements for dquots, log grant code cleanups, plus
bugfixes and cleanups large and small"
Fix up various trivial conflicts that were due to some of the earlier
patches already having been integrated into v3.3 as bugfixes, and then
there were development patches on top of those. Easily merged by just
taking the newer version from the pulled branch.
