From 25435e5ed611f310dda889940cbc4c45b3ecd9ec Mon Sep 17 00:00:00 2001 From: Abhi Das Date: Wed, 18 Mar 2015 12:04:37 -0500 Subject: [PATCH] gfs2: allow quota_check and inplace_reserve to return available blocks struct gfs2_alloc_parms is passed to gfs2_quota_check() and gfs2_inplace_reserve() with ap->target containing the number of blocks being requested for allocation in the current operation. We add a new field to struct gfs2_alloc_parms called 'allowed'. gfs2_quota_check() and gfs2_inplace_reserve() return the max blocks allowed by quota and the max blocks allowed by the chosen rgrp respectively in 'allowed'. A new field 'min_target', when non-zero, tells gfs2_quota_check() and gfs2_inplace_reserve() to not return -EDQUOT/-ENOSPC when there are atleast 'min_target' blocks allowable/available. The assumption is that the caller is ok with just 'min_target' blocks and will likely proceed with allocating them.
