| |
hi,
why is it FORCED ? bypassing a GLOBAL setting and also the kernel command line !!!
drivers/s390/block/dasd.c
/* * Allocate and initialize request queue and default I/O scheduler. */ static int dasd_alloc_queue(struct dasd_block *block) { int rc;
block->request_queue = blk_init_queue(do_dasd_request, &block->request_queue_lock); if (block->request_queue == NULL) return -ENOMEM;
block->request_queue->queuedata = block;
elevator_exit(block->request_queue->elevator); block->request_queue->elevator = NULL; rc = elevator_init(block->request_queue, "deadline"); if (rc) { blk_cleanup_queue(block->request_queue); return rc; } return 0; }
-thanks-
