From 20e73b000bcded44a91b79429d8fa743247602ad Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 3 Jan 2017 18:39:33 -0800 Subject: xfs: use the actual AG length when reserving blocks We need to use the actual AG length when making per-AG reservations, since we could otherwise end up reserving more blocks out of the last AG than there are actual blocks.
