From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Hellwig Subject: fix large I/O regression with iSER in 4.4+ Date: Mon, 11 Apr 2016 15:47:24 -0700 Message-ID: <1460414846-29540-1-git-send-email-hch@lst.de> Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-scsi-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-scsi@vger.kernel.org Since iSER was converted to use the generic virt_boundary mechanism (which was called something else in 4.4), it didn't handle the case where a request is using up the full size of max_hw_segments, but not actually aligned to the virt boundary. This series sets the maximum segment size limit to fix this workload (xfs_repair is a good reproducer, btw). Should probably go into 4.4 and 4.5-stable. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
