From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx> Subject: [PATCH] ide: add "flagged" taskfile flags to struct ide_taskfile * Add ->ftf_flags field to struct ide_taskfile and convert flags for TASKFILE ioctl to use it. * Rename "flagged" taskfile flags: - IDE_TFLAG_FLAGGED -> IDE_FTFLAG_FLAGGED - IDE_TFLAG_FLAGGED_SET_IN_FLAGS -> IDE_FTFLAG_SET_IN_FLAGS - IDE_TFLAG_{OUT,IN}_DATA -> IDE_FTFLAG_{OUT,IN}_DATA There should be no functional changes caused by this patch.
