[PATCH 02/16] GFS2: Fold quota data into the reservations struct

From: Steven Whitehouse
Date: Mon Jul 23 2012 - 04:29:24 EST

From: Bob Peterson <rpeterso@xxxxxxxxxx>

This patch moves the ancillary quota data structures into the
block reservations structure. This saves GFS2 some time and
effort in allocating and deallocating the qadata structure.
