| * [BLOCK] Clear sg entry before filling in blk_rq_map_sg()Jens Axboe2007-10-17
| | | | | | | | | | | | | | | | The memset() of the sg entry was originally removed, because it could overwrite a chain pointer. But it's quite OK to memset() it when we know it's a valid entry, since it can't contain a chain pointer. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* Drop 'size' argument from bio_endio and bi_end_ioNeilBrown2007-10-10
| | | | | | | | | | | | | As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void.

* Don't decrement bi_size in bio_endioNeilBrown2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | The only caller of bio_endio that does not pass the full bi_size is end_that_request_first. Also, no ->bi_end_io method is really interested in bi_size being decremented. So move the decrement and related code into ll_rw_blk and merge it with order_bio_endio to form req_bio_endio which does endio functionality specific to request completion. As some ->bi_end_io methods do check bi_size of 0, we set it thus for now, but that will go in the next patch.

* Merge blk_recount_segments into blk_recalc_rq_segmentsNeilBrown2007-10-10
| | | | | | | | | | | | | | | | | | | blk_recalc_rq_segments calls blk_recount_segments on each bio, then does some extra calculations to handle segments that overlap two bios. If we merge the code from blk_recount_segments into blk_recalc_rq_segments, we can process the whole request one bio_vec at a time, and not need the messy cross-bio calculations. Then blk_recount_segments can be implemented by calling blk_recalc_rq_segments, passing it a simple on-stack request which stores just the bio.

* shared tag queue barrier commentNick Piggin2007-09-14

* Fix race with shared tag queue mapsJens Axboe2007-09-13
| | | | | | | | | | | | | | | | | | | | | | There's a race condition in blk_queue_end_tag() for shared tag maps, users include stex (promise supertrak thingy) and qla2xxx. The former at least has reported bugs in this area, not sure why we haven't seen any for the latter. It could be because the window is narrow and that other conditions in the qla2xxx code hide this. It's a real bug, though, as the stex smp users can attest. We need to ensure two things - the tag bit clearing needs to happen AFTER we cleared the tag pointer, as the tag bit clearing/setting is what protects this map. Secondly, we need to ensure that the visibility of the tag pointer and tag bit clear are ordered properly.
