Subject[PATCH 3.16 025/233] dm thin metadata: call precommit before saving the roots
3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Joe Thornber <ejt@redhat.com>

commit 91bcdb92d39711d1adb40c26b653b7978d93eb98 upstream.

These calls were the wrong way round in __write_initial_superblock.
