I goofed and commented in the order I saw the patches :) I take this
comment back for this patch, because I see in 16/16 you added a new
workqueue to scsi_dh_alua to do rtpgs and stpgs.

For 16/16 though, do we want to make kmpath_aluad a non single threaded
workqueue? It looks like max_active for single threaded is only one work
at a time too.
