From 89d4346a36a00ab1f9bd71f929564e9fc1c7c539 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Wed, 15 Jan 2014 20:00:57 +0800 Subject: [PATCH] Btrfs: fix wrong block group in trace during the free space allocation We allocate the free space from the former block group, not the current one, so should use the former one to output the trace information.
