From 564e12b1157215171e7f3af5b70611ec7154327c Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Mon, 21 Nov 2011 13:36:17 -0500 Subject: GFS2: decouple quota allocations from block allocations This patch separates the code pertaining to allocations into two parts: quota-related information and block reservations. This patch also moves all the block reservation structure allocations to function gfs2_inplace_reserve to simplify the code, and moves the frees to function gfs2_inplace_release.
