2008-12-29nbd: tell the block layer that it is not a rotational deviceJens Axboe1-6/+4
Then we can get rid of that manual elevator type fiddling. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29block: get rid of elevator_t typedefJens Axboe1-1/+1
Just use struct elevator_queue everywhere instead. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29bio: allow individual slabs in the bio_setJens Axboe3-3/+3
Instead of having a global bio slab cache, add a reference to one in each bio_set that is created. This allows for personalized slabs in each bio_set, so that they can have bios of different sizes. This means we can personalize the bios we return. File systems may want to embed the bio inside another structure, to avoid allocation more items (and stuffing them in ->bi_private) after the get a bio. Or we may want to embed a number of bio_vecs directly at the end of a bio, to avoid doing two allocations to return a bio. This is now possible. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29cciss: switch to using hlist for command list managementJens Axboe3-46/+33

2008-12-29xen-blkfront: set queue paravirt flagFernando Luis Vázquez Cao1-7/+1
Xen's blkfront sets noop as the default I/O scheduler at initialization time to avoid elevator overheads such as idling, but with the advent of basic disk profiling capabilities this is not necessary anymore. We should just tell the block layer that we are a paravirt front-end driver and the elevator will automatically make the necessary adjustments.

2008-12-29virtio_blk: set queue paravirt flagFernando Luis Vázquez Cao1-0/+2
