The patch titled
ext2 balloc: fix off-by-one against grp_goal
has been removed from the -mm tree. Its filename was
ext2-balloc-fix-off-by-one-against-grp_goal.patch
This patch was dropped because it was folded into ext2-reservations.patch
------------------------------------------------------
Subject: ext2 balloc: fix off-by-one against grp_goal
From: Hugh Dickins <hugh@xxxxxxxxxxx>
grp_goal 0 is a genuine goal (unlike -1), so ext2_try_to_allocate_with_rsv
should treat it as such.
