2023-04-13T12:52:30+00:00

blk_mq_add_to_requeue_list takes a bool parameter to control how to kick the requeue list at the end of the function. Move the call to blk_mq_kick_requeue_list to the callers that want it instead.

block: change request end_io handler to pass back a return value

2022-09-30T13:49:09+00:00

Everything is just converted to returning RQ_END_IO_NONE, and there should be no functional changes with this patch. In preparation for allowing the end_io handler to pass ownership back to the block layer, rather than retain ownership of the request. Reviewed-by: Keith Busch Signed-off-by: Jens Axboe

block: kill deprecated BUG_ON() in the flush handling

2022-09-30T13:48:00+00:00

We've never had any useful reports from this BUG_ON(), and in fact a number of the BUG_ON()'s in the flush handling need to be turned into more graceful handling. In preparation for allowing batched completions of the end_io handling, where we can enter the flush completion with queuelist having been reused for the batch, get rid of this BUG_ON().
