2023-02-03blk-cgroup: pin the gendisk in struct blkcg_gqChristoph Hellwig
Currently each blkcg_gq holds a request_queue reference, which is what is used in the policies. But a lot of these interfaces will move over to use a gendisk, so store a disk in struct blkcg_gq and hold a reference to it.

2023-02-03blk-cgroup: simplify blkg freeing from initialization failure pathsChristoph Hellwig
There is no need to delay freeing a blkg to a workqueue when freeing it after an initialization failure. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Tejun Heo <tj@kernel.org> Link: https://lore.kernel.org/r/20230203150400.3199230-5-hch@lst.de Signed-off-by: Jens Axboe <axboe@kernel.dk>
2023-02-03blk-cgroup: improve error unwinding in blkg_allocChristoph Hellwig
Unwind only the previous initialization steps that happened in blkg_alloc using goto based unwinding. This avoids the need for the !queue special case in blkg_free and thus ensures that any blkg seens outside of blkg_alloc is always fully constructed.

2023-02-03blk-cgroup: delay blk-cgroup initialization until add_diskChristoph Hellwig
There is no need to initialize the cgroup code before the disk is marked live. Moving the cgroup initialization earlier will help to have a fully initialized struct device in the gendisk for the cgroup code to use in the future. Similarly tear the cgroup information down in del_gendisk to be symmetric and because none of the cgroup tracking is needed once non-passthrough I/O stops.

2023-02-03block: don't call blk_throtl_stat_add for non-READ/WRITE commandsChristoph Hellwig
blk_throtl_stat_add is called from blk_stat_add explicitly, unlike the other stats that go through q->stats->callbacks. To prepare for cgroup data moving to the gendisk, ensure blk_throtl_stat_add is only called for the plain READ and WRITE commands that it actually handles internally, as blk_stat_add can also be called for passthrough commands on queues that do not have a gendisk associated with them.
