Subject: [PATCH 1/3] Remove race for starting container devices.
commit 5fc8cff3a4177dfbab594947283117620b4b8c9c
Author: Jes Sorensen <Jes.Sorensen@redhat.com>
Date: Sat Oct 22 11:29:47 2011 +1100
Remove race for starting container devices.
This moves the lock handling out of Incremental_container() and relies
on the caller holding the lock. This prevents conflict with a
follow-on mdadm comment which may try and launch the device in
parallel.
This involves replacing a call to "Incremental" with an
unrolled version with just the case that calls Incremental_container
and so needs a call to ->load_container.
