The only real issue here would be an immediate struct Scsi_Host->host_lock dead lock for those LLDs that still use legacy unlock() > do_work() -> lock() in their SHT->queuecommand() caller. This is *not* going to happen under heavy load with a bunch of outstanding WRITEs, but immediate the first couple of times that scsi_dispatch_cmd() gets called, so there is really little to no fear of filesystem corruption with these patches. Anyways, please feel free to test them yourself with an TMR ABORT storm if you so desire..
