GFS2: Use generic list_lru for quota (2013-11-04 11:17:49 +0000)

The main feature of interest this time is quota updates. There are
some clean ups and some patches to use the new generic lru list
code. There is still plenty of scope for some further changes in
due course - faster lookups of quota structures is very much
on the todo list. Also, a start has been made towards the more tricky
issue of using the generic lru code with glocks, but that will
have to be completed in a subsequent merge window.

The other, more minor feature, is that there have been a number of
performance patches which relate to block allocation. In particular
they will improve performance when the disk is nearly full.
