From 90ce321da8ce3d00e19586993887346286208386 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Mon, 26 Oct 2015 14:11:19 +0800 Subject: [PATCH] btrfs: qgroup: Fix a rebase bug which will cause qgroup double free When rebasing my patchset, I forgot to pick up a cleanup patch to remove old hotfix in 4.2 release. Witouth the cleanup, it will screw up new qgroup reserve framework and always cause minus reserved number.
