Subject: [PATCH] 3/4: DM: dm-raid1.c: Enforce max of 9 mirrors
Date: Wed, 30 Jun 2004 14:58:27 -0500	[thread overview]
Message-ID: <200406301458.27773.kevcorry@us.ibm.com> (raw)
In-Reply-To: <200406301452.16886.kevcorry@us.ibm.com>

dm-raid1.c: Since kcopyd can currently only handle 1 source and up to 8
destinations, enforce a max of 9 mirrors when creating a dm-mirror device.

Signed-off-by: Kevin Corry <kevcorry@us.ibm.com>
