From 5ed1617731a1e9201c3541a9c05ce3ec73975589 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 29 Aug 2012 17:11:07 -0500 Subject: rbd: call set_snap() before snap_devs_update() rbd_header_set_snap() is a simple initialization routine for an rbd device's mapping. It has to be called after the snapshot context for the rbd_dev has been updated, but can be done before snapshot devices have been registered. Change the name to rbd_dev_set_mapping() to better reflect its purpose, and call it a little sooner, before registering snapshot devices.
