Removing the lock entirely and pushing the list into the two drivers using it is on my TODO list. Bart actually suggested keeping the code in the SCSI core and having a flag to enabled. Given that I'm too busy to get my full version done in time, it might be a good idea if someone picks up Barts idea. Can you send me a patch to add a enable_cmd_list flag to the host template and only enable it for aacraid and dpt_i2o? -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
