* ide-{floppy,tape}: fix padding for PIO transfersBartlomiej Zolnierkiewicz2009-03-31
| | | | | | | | | | | | | | | | | | | | | * Return number of bytes left to transfer from idetape_{in,out}put_buffers() and number of bytes done from ide_tape_io_buffers(). * Fix padding for PIO transfers in ide_pc_intr() so read/write buffers are always completely processed and then the transfer is padded if necessary. * Remove invalid error messages. * Remove now superfluous padding from ide{_io_buffers,tape_input_buffers}(). While at it: * Set pc->bh to NULL in idetape_input_buffers() after all bh-s are done. * Cache !!(pc->flags & PC_FLAG_WRITING) in local variable in ide_pc_intr().

* ide: decrease size of ->pc_buf field in struct ide_atapi_pcBartlomiej Zolnierkiewicz2009-03-31
| | | | | | | | | | struct ide_atapi_pc is often allocated on the stack and size of ->pc_buf size is 256 bytes. However since only ide_floppy_create_read_capacity_cmd() and idetape_create_inquiry_cmd() require such size allocate buffers for these pc-s explicitely and decrease ->pc_buf size to 64 bytes.

* ide: use do_rw_taskfile() for ATA_CMD_PACKET commandsBartlomiej Zolnierkiewicz2009-03-27
| | | | | | | | | | | | | | | | | | * Pass command to ide_issue_pc() and update ->do_request methods in ide-{cd,floppy,tape}.c accordingly. * Convert ide_pktcmd_tf_load() to ide_init_packet_cmd() which just initializes command structure and use do_rw_taskfile() to load ATA_CMD_PACKET commands. While at it: * Rename ide{floppy,tape}_issue_pc() to ide_{floppy,tape}_issue_pc(). There should be no functional changes caused by this patch.

* ide: fix refcounting in device driversBartlomiej Zolnierkiewicz2009-02-25
| | | | | | | | | | | | | | | | During host driver module removal del_gendisk() results in a final put on drive->gendev and freeing the drive by drive_release_dev(). Convert device drivers from using struct kref to use struct device so device driver's object holds reference on ->gendev and prevents drive from prematurely going away. Also fix ->remove methods to not erroneously drop reference on a host driver by using only put_device() instead of ide*_put().

* [PATCH] beginning of methods conversionAl Viro2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
