Hi James, The following patches exports busy-status of SCSI LLD to request-based dm-multipath for proper I/O scheduling. The patches are created on the following commit of scsi-misc-2.6. --------------------------------------------------------------- commit 7d36ee8aefec15ab00ac08dc5611d6b5eab38d7f Author: Andrew Vasquez <andrew.vasquez@xxxxxxxxxx> Date: Thu Sep 11 21:22:54 2008 -0700 [SCSI] qla2xxx: Update version number to 8.02.01-k8. --------------------------------------------------------------- No major changes since the last post (http://lkml.org/lkml/2008/9/12/100), except for rebasing on top of scsi-misc-2.6 from 2.6.27-rc6. Summary of the patches: 1/2: lld busy status exporting interface 2/2: scsi: exports busy status via bdi_lld_congested Please review and apply. The 1st patch changes generic part and not specific to scsi, so I'm not sure whether it is appropriate to ask you about merging this patch. If I should push the 1st patch separately to other person, please let me know. Thanks, Kiyoshi Ueda -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
