Hi all, as promised here is now the second part of my ALUA device handler update. This contains a major rework of the ALUA device handler as execution is moved onto a workqueue. This has the advantage that we avoid having to do multiple calls to the same LUN (as happens frequently when failing over a LUN with several paths) and finally retries are handled correctly. As some arrays are only capable of handling one STPG at a time I've added a module parameter 'sync_stpg' which switches to a singlethreaded workqueue, thereby effectively synchronize STPG handling. Thanks to Bart for this suggestion. As usual, comments and reviews are welcome.
As I've been reminded a git reference would be welcome for review. So you can find the entire patchset at git://git.kernel.org/pub/scm/linux/kernel/git/hare/scsi-devel.git branch alua.v8 Cheers, Hannes -- Dr. Hannes Reinecke zSeries & Storage hare@xxxxxxx +49 911 74053 688 SUSE LINUX GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: F.
