Hi Bart, This patchset refits the tape->merge_stage pipeline stage into tape->bh, a singly linked list of idetape_bh's, each of which is a tag attached to one or more pages serving as a buffer for data requests. The original functionality is kept wrt collecting data in the buffer and flushing it to the hardware when full. Currently, the data rq's are serialized on the block interface and it would probably be better to return immediately after issuing it over ide_do_drive_cmd() in order to increase throughput, proper locking and testing implied of course. drivers/ide/ide-tape.c | 393 +++++++++++++++++------------------------------- 1 files changed, 135 insertions(+), 258 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
