[PATCH 04/19] btrfs: Push mnt_want_write() outside of i_mutex

When mnt_want_write() starts to handle freezing it will get a full lock semantics requiring proper lock ordering. So push mnt_want_write() call consistently outside of i_mutex. CC: Chris Mason chris.ma...@oracle.com CC: linux-btrfs@vger.kernel.org Signed-off-by: Jan Kara j...@suse.cz ---
