For the request based multipath I thought I would need to run some code when a command times out. I did not want to duplicate the scsi code, so I did the following patches which move the scsi timer code to the block layer then convert scsi. I have tested the scsi_error.c and normal paths with iscsi. And, I have tested the normal IO paths with libata. Since libata uses the strategy handler it needs to be tested a lot more. Some of the drivers that were touching the timeout_per_command field need to be compile tested still too. I converted them, but I think some still need a "#include blkdev.h". The patches only move the scsi timer code to the block layer and hook it in so others can use it. I have not started on the abort, reset and quiesce code since it is not really needed for multipath. I wanted to see if the timer code move was ok on its own without the rest of the scsi eh move because I do not want to manage the patches out of tree with the other request multipath patches. I also wanted to check if the scsi timer code was ok in general. Maybe scsi got it wrong and needed to be rewritten :) Both patches were made over 2.6.18-rc2. - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
