Subject: [PATCH] 07reshape5intr: Set speed_limit_min to be able to reduce resync speed below 1000
Date: Wed, 11 Jul 2012 09:53:06 +0200 [thread overview]
Message-ID: <1341993186-8207-1-git-send-email-Jes.Sorensen@redhat.com> (raw)
From: Jes Sorensen <Jes.Sorensen@redhat.com>
We need to set speed_limit_min accordingly, otherwise setting
speed_limit_max below 1000 will have no effect.
Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com>
