From 3ee4001e0c875ce8ebcdf5ea305e9a105b3687bd Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 29 Aug 2012 17:11:07 -0500 Subject: rbd: set up watch before announcing disk We're ready to handle header object (refresh) events at the point we call rbd_bus_add_dev(). Set up the watch request on the rbd image header just after that, and after we've registered the devices for the snapshots for the initial snapshot context. Do this before announce the disk as available for use.
