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



From: Bob Peterson <rpeterso redhat com>

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.
