From f42a34b2f10c411ef45f247f3000ed03ba4e80c0 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Thu, 11 Apr 2013 10:29:35 +0000 Subject: Btrfs: fix unblocked autodefraggers when remount The new mount option is set after parsing the remount arguments, so it is wrong that checking the autodefrag is close or not at btrfs_remount_prepare(). Fix it.
