block: change the blk_queue_bounce calling convention

2022-08-02T23:22:54+00:00

The double indirect bio leads to somewhat suboptimal code generation. Instead return the (original or split) bio, and make sure the request_queue arguments to the lower level helpers is passed after the bio to avoid constant reshuffling of the argument passing registers.

block: remove superfluous calls to blkcg_bio_issue_init

2022-05-05T00:29:52+00:00

blkcg_bio_issue_init is called in submit_bio. There is no need to have extra calls that just get overriden in __bio_clone and the two places that copy and pasted from it.

Merge tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block

2022-03-26T18:51:46+00:00

Pull NVMe write streams removal from Jens Axboe: "This removes the write streams support in NVMe. No vendor ever really shipped working support for this, and they are not interested in supporting it. With the NVMe support gone, we have nothing in the tree that supports this. Remove passing around of the hints. The only discussion point in this patchset imho is the fact that the file specific write hint setting/getting fcntl helpers will now return -1/EINVAL like they did before we supported write hints. No known applications use these functions, I only know of one prototype that I help do for RocksDB, and that's not used. That said, with a change like this, it's always a bit controversial. Alternatively, we could just make them return 0 and pretend it worked. It's placement based hints after all" * tag 'for-5.18/write-streams-2022-03-18' of git://git.kernel.dk/linux-block: fs: remove fs.f_write_hint fs: remove kiocb.ki_hint block: remove the per-bio/request write hint nvme: remove support or stream based temperature hint

block: pass a block_device and opf to bio_alloc_bioset

2022-02-02T14:49:59+00:00

Pass the block_device and operation that we plan to use this bio for to bio_alloc_bioset to optimize the assigment. NULL/0 can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code. Also move the gfp_mask argument after the nr_vecs argument for a much more logical calling convention matching what most of the kernel does.
