| |
Are we going to use the queue_wait field of struct request_queue someday? As of 2.6.0-test2, I don't see any use of it. If it's not needed anymore, the following patch gets rid of it. Tested this patch by compiling for i386 and also doing a grep through all .h and .c files to see if it's used somewhere else (admittedly weak). diff -urN linux-2.6.0-test2/drivers/block/ll_rw_blk.c linux-2.6.0-test2-no_queue_wait/drivers/block/ll_rw_blk.c --- linux-2.6.0-test2/drivers/block/ll_rw_blk.c 2003-07-27 19:02:48.000000000 -0600 +++ linux-2.6.0-test2-no_queue_wait/drivers/block/ll_rw_blk.c 2003-07-27 22:36:16.000000000 -0600 @@ -225,7 +225,6 @@ */ blk_queue_bounce_limit(q, BLK_BOUNCE_HIGH); - init_waitqueue_head(&q->queue_wait); INIT_LIST_HEAD(&q->plug_list); } diff -urN linux-2.6.0-test2/include/linux/blkdev.h linux-2.6.0-test2-no_queue_wait/include/linux/blkdev.h --- linux-2.6.0-test2/include/linux/blkdev.h 2003-07-27 19:02:52.000000000 -0600 +++ linux-2.6.0-test2-no_queue_wait/include/linux/blkdev.h 2003-07-27 22:18:19.000000000 -0600 @@ -337,8 +337,6 @@ unsigned long seg_boundary_mask; unsigned int dma_alignment; - wait_queue_head_t queue_wait; - struct blk_queue_tag *queue_tags; /* | |
