Subject: [PATCH] ioatdma: allow all channels to have irq coalescing support
Date: Tue, 26 Feb 2013 09:20:36 -0700	[thread overview]
Message-ID: <20130226162036.4996.78263.stgit@djiang5-linux2.ch.intel.com> (raw)

Looks like only the RAID channels are allowed to have irq coalescing support
in the existing code. Fixing that. The ioat3 cleanup code can handle memcpy
ops anyways
