rnbd-srv: use bdev_discard_alignment

2022-05-03T16:38:50Z

Use bdev_discard_alignment to calculate the correct discard alignment offset even for partitions instead of just looking at the queue limit.

block/rnbd-clt: Avoid flush_workqueue(system_long_wq) usage

2022-04-18T15:24:56Z

Flushing system-wide workqueues is dangerous and will be forbidden. Replace system_long_wq with local rnbd_clt_wq.

block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD

2022-04-18T01:49:59Z

Secure erase is a very different operation from discard in that it is a data integrity operation vs hint. Fully split the limits and helper infrastructure to make the separation more clear.

block: remove QUEUE_FLAG_DISCARD

2022-04-18T01:49:59Z

Just use a non-zero max_discard_sectors as an indicator for discard support, similar to what is done for write zeroes. The only places where needs special attention is the RAID5 driver, which must clear discard support for security reasons by default, even if the default stacking rules would allow for it.

block: add a bdev_max_discard_sectors helper

2022-04-18T01:49:59Z

Add a helper to query the number of sectors support per each discard bio based on the block device and use this helper to stop various places from poking into the request_queue to see if discard is supported and if so how much. This mirrors what is done e.g. for write zeroes as well. Signed-off-by: Christoph Hellwig Reviewed-by: Martin K.

blk-mq: prepare for implementing hctx table via xarray

2022-03-09T00:57:19Z

It is inevitable to cause use-after-free on q->queue_hw_ctx between queue_for_each_hw_ctx() and blk_mq_update_nr_hw_queues(). And converting to xarray can fix the uaf, meantime code gets cleaner. Prepare for converting q->queue_hctx_ctx into xarray, one thing is that xa_for_each() can only accept 'unsigned long' as index, so changes type of hctx index of queue_for_each_hw_ctx() into 'unsigned long'.
