Subject: dm raid1: switch rh_in_sync to blocking in do_reads
From: Jonathan Brassow <jbrassow@xxxxxxxxxx>
The call to rh_in_sync() in do_reads() should be allowed to block. It is in
the mirror worker thread which already permits blocking operations. This will
be needed to support clustered mirroring which will perform network
operations.
