Subject: [RESEND] [PATCH] ipr: Rate limit DMA mapping errors
Date: Tue, 17 May 2011 09:58:35 -0700 [thread overview]
Message-ID: <4DD2A93B.3000006@linux.vnet.ibm.com> (raw)
Resending this based on James' request that was sent to the
linux-scsi list on May 10.
---
I noticed a stream of errors from the IPR driver while doing
IOMMU fault injection. Rate limit the errors so we don't clog
up the console and logfiles.
