Subject: [PATCH] MD: generate an event when array sync is complete
Date: Thu, 14 Jul 2011 15:59:25 -0500 [thread overview]
Message-ID: <1310677165.2246.12.camel@f14.redhat.com> (raw)
Neil,
I'm not sure this is the best place in the code to put this (even though
I've tested that it works well). I welcome your corrections.

This patch causes MD to generate an event (for device-mapper) once array
synchronization is complete. This is expected behavior for device-mapper.
