From 74095a91ed02f6727b62d4416be00a041f2d7436 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:07 +0100 Subject: ide: use do_rw_taskfile() in flagged_taskfile() Based on the earlier work by Tejun Heo. * Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile() function to the callers. * Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming from ide_taskfile_ioctl(). Check it instead of ->tf_out_flags.all. * Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load IDE data register in ide_tf_load(). * Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load particular IDE taskfile registers in ide_tf_load(). * Update do_rw_taskfile() and ide_tf_load() users to set respective IDE_TFLAG_OUT_* taksfile flags. * Add task_dma_ok() helper. * Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load(). * Use do_rw_taskfile() in flagged_taskfile(). * Remove no longer needed 'tf_out_flags' field from ide_task_t. There should be no functionality changes caused by this patch.
