2008-02-01ide-cd: prepare cdrom_rw_intr() and cdrom_newpc_intr() to be mergedBartlomiej Zolnierkiewicz
In cdrom_newpc_intr(): * cleanup variables in the 'transfer data' loop In cdrom_rw_intr(): * rename 'sectors_to_transfer' to 'thislen' * rename 'this_transfer' to 'blen' * keep number of bytes (instead of sectors) in 'thislen' and 'blen' * call 'xferfunc' only once for 'blen' * cache 'rq->buffer' in 'ptr' variable * check for 'rq->bio' before setting 'ptr' and 'blen' * check for 'ptr' instead of 'rq->current_nr_sectors' There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-01ide-cd: unify moving to the next buffer in cdrom_rw_intr()Bartlomiej Zolnierkiewicz
Use the fact that for the first loop rq->current_nr_sectors is always set and unify moving to the next buffer for read/write requests. There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-01ide-cd: merge cdrom_start_read() and cdrom_start_write()Bartlomiej Zolnierkiewicz
Add handling of read requests to cdrom_start_write(), rename it to cdrom_start_rw() and remove no longer needed cdrom_start_read(). There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-01ide-cd: merge cdrom_start_read_continuation() and cdrom_start_rw_cont()Bartlomiej Zolnierkiewicz

There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
