GFS2: revert "GFS2: d_splice_alias() can't return error" (2014-01-18 09:50:53 +0000)

The main topics this time are allocation, in the form of Bob's
improvements when searching resource groups and several updates
to quotas which should increase scalability. The quota changes
follow on from those in the last merge window, and there will
likely be further work to come in this area in due course.

There are also a few patches which help to improve efficiency
of adding entries into directories, and clean up some of that

One on-disk change is included this time, which is to write some
additional information which should be useful to fsck and
also potentially for debugging.

Other than that, its just a few small random bug fixes and
clean ups.
