these have been wrappers for the generic dma direction bits since 2.5.x.
This patch converts the few remaining drivers and removes the macros.
Arjan noticed there's some hunk in here that shouldn't. Updated patch
below:
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
implicitly have a direction attribute setting of
PCI_DMA_BIDIRECTIONAL.
-The SCSI subsystem provides mechanisms for you to easily obtain
-the direction to use, in the SCSI command:
-
- scsi_to_pci_dma_dir(SCSI_DIRECTION)
-
-Where SCSI_DIRECTION is obtained from the 'sc_data_direction'
-member of the SCSI command your driver is working on. The
-mentioned interface above returns a value suitable for passing
-into the streaming DMA mapping interfaces below.
+The SCSI subsystem tells you the direction to use in the
+'sc_data_direction' member of the SCSI command your driver is
+working on.
For Networking drivers, it's a rather simple affair. For transmit
packets, map/unmap them with the PCI_DMA_TODEVICE direction
scsi_remove_host - detach and remove all SCSI devices owned by host
scsi_report_bus_reset - report scsi _bus_ reset observed
scsi_set_device - place device reference in host structure
- scsi_to_pci_dma_dir - convert SCSI subsystem direction flag to PCI
- scsi_to_sbus_dma_dir - convert SCSI subsystem direction flag to SBUS
scsi_track_queue_full - track successive QUEUE_FULL events
scsi_unblock_requests - allow further commands to be queued to given host
scsi_unregister - [calls scsi_host_put()]
