I want fully-flagged taskfile handling like flagged_taskfile() and "hot path"
simpler taskfile handling like do_rw_taskfile() (at le

Oh, Bartlomiej, one more thing.
If it isn't too much trouble, can you please set up a bk repository
which contains the patches you've posted and whatever you're working on
but hasn't yet made into ide-dev tree? So that we don't have to juggle
patches back and forth. If you maintain your up-t
Hello, Bartlomiej.
Hello, Jeff.

Hello, Bartlomiej.
This patch should be modified to use flagged taskfile if the
task_end_request_fix patch isn't applied. As non-flagged taskfile
won't return valid result registers, TASK ioctl users won't get the
correct register output.
IMHO, this flag-to-get-result-registers thing is way t
ide_task_ioctl() rewritten to use taskfile transport.
This is the last user of REQ_DRIVE_TASK.
