Subject: [PATCH] ide: use blk_fs_request() check in ide-taskfile.c
Use blk_fs_request() in ide-taskfile.c instead of checking for:
- rq->bio in ide_pio_datablock() and task_error()
- rq->cmd_type == REQ_TYPE_ATA_TASKFILE in task_end_request()
There should be no functional changes caused by this patch.

Subject: [PATCH] ide: remove ide_task_t typedef
While at it:
- rename struct ide_task_s to struct ide_cmd
- remove stale comments from idedisk_{read_native,set}_max_address()
- drop unused 'cmd' argument from ide_{cmd,task}_ioctl()
- drop unused 'task' argument from tx4939ide_tf_load_fixup()
- rename ide_complete_task() to ide_complete_cmd()
- use consistent naming for struct ide_cmd variables
There should be no functional changes caused by this patch.

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ide: pass command instead of request to ide_pio_datablock()
* Add IDE_TFLAG_FS taskfile flag and set it for REQ_TYPE_FS requests.
* Convert ->{in,out}put_data methods to take command instead of request
as an argument. Then convert pre_task_out_intr(), task_end_request(),
task_error(), task_in_unexpected(), ide_pio_sector(), ide_pio_multi()
and ide_pio_datablock() in similar way.
* Rename task_end_request() to ide_finish_cmd().
There should be no functional changes caused by this patch.

Subject: [PATCH] ide: move command related fields from ide_hwif_t to struct ide_cmd
* Move command related fields from ide_hwif_t to struct ide_cmd.
* Make ide_init_sg_cmd() take command and sectors number as arguments.
There should be no functional changes caused by this patch.

Subject: [PATCH] ide: set IDE_TFLAG_WRITE basing on data phase used in ide_taskfile_ioctl()
Also take care of fixing up incorrect TASKFILE_IN_DMA[Q] data phase when
IDE_DRIVE_TASK_RAW_WRITE is requested (no need to do it for TASKFILE_NO_DATA
and TASKFILE_[MULTI]_IN -- it had no chance of working previously).

Subject: [PATCH] ide: use ata_tf_protocols enums
* Add IDE_TFLAG_MULTI_PIO taskfile flag and set it for commands
using multi-PIO protocol.
* Use ata_tf_protocols enums instead of TASKFILE_* defines to
denote command's protocol and then rename ->data_phase field
to ->protocol.
* Remove no longer needed <linux/hdreg.h> includes.
There should be no functional changes caused by this patch.
