From 2456242530a21cfee82646ebeeda65d3f74faa4c Mon Sep 17 00:00:00 2001 From: Yan Zheng Date: Thu, 12 Feb 2009 14:14:53 -0500 Subject: Btrfs: hold trans_mutex when using btrfs_record_root_in_trans btrfs_record_root_in_trans needs the trans_mutex held to make sure two callers don't race to setup the root in a given transaction. This adds it to all the places that were missing it.
