Hi James,
The following patches export 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-post-merge-2.6. --------------------------------------------------------------- commit 454f40af9f0d4cda1c89e1fc0028d5235b150bc7 Author: Mike Christie <michaelc@cs.wisc.edu> Date: Wed Sep 24 11:46:15 2008 -0500
libiscsi: fix locking in iscsi_eh_device_reset ---------------------------------------------------------------
The changes from the previous version (*) is to check the busy state everytime instead of using a cached flag inside scsi.
Summary of the patches: 1/2: scsi: refactor sdev/starget/shost busy checking 2/2: scsi: export busy state via q->lld_busy_fn()
Please review and apply.
Thanks, Kiyoshi Ueda
