1e1a9cec - block: force noio scope in blk_mq_freeze_queue

Fri, 31 Jan 2025 12:03:47 +0000

block: force noio scope in blk_mq_freeze_queueWhen block drivers or the core block code perform allocations with afrozen queue, this could try to recurse into the block device toreclaim memory and deadlock. Thus all allocations done by a processthat froze a queue need to be done without __GFP_IO and __GFP_FS.Instead of tying to track all of them down, force a noio scope aspart of freezing the queue.Note that nvme is a bit of a mess here due to the non-owner freezes,and they will be addressed separately.Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20250131120352.1315351-2-hch@lst.deSigned-off-by: Jens Axboe List of files: /linux-6.15/drivers/block/swim3.c

block: remove BLK_MQ_F_SHOULD_MERGEBLK_MQ_F_SHOULD_MERGE is set for all tag_sets except those that purelyprocess passthrough commands (bsg-lib, ufs tmf, various nvme adminqueues) and thus don't even check the flag.

bd4a633b - block: move the nonrot flag to queue_limits

Mon, 17 Jun 2024 06:04:41 +0000

block: move the nonrot flag to queue_limitsMove the nonrot flag into the queue_limits feature field so that it canbe set atomically with the queue frozen.Use the chance to switch to defaulting to non-rotational and requirethe driver to opt into rotational, which matches the polarity of thesysfs interface.For the z2ram, ps3vram, 2x memstick, ubiblock and dcssblk the newrotational flag is not set as they clearly are not rotational despitethis being a behavior change. There are some other drivers thatunconditionally set the rotational flag to keep the existing behavioras they arguably can be used on rotational devices even if that isprobably not their main use today (e.g. virtio_blk and drbd).The flag is automatically inherited in blk_stack_limits matching theexisting behavior in dm and md.Signed-off-by: Christoph Hellwig Reviewed-by: Damien Le Moal Reviewed-by: Hannes Reinecke Link: https://lore.kernel.org/r/20240617060532.127975-15-hch@lst.deSigned-off-by: Jens Axboe List of files: /linux-6.15/drivers/block/swim3.c

Revert "block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers"This reverts commit 9fd097b14918875bd6f125ed699d7bbbba5893ee.Instead of leaving disk->events completely empty, we now export thesupported events again, and tell the block layer not to forward events touser space by not setting DISK_EVENT_FLAG_UEVENT. This allows the blocklayer to distinguish between devices that for which events should behandled in kernel only, and devices which don't support any meda changeevents at all.Cc: Jiri Kosina Cc: Tim Waugh Cc: Michal Simek Reviewed-by: Hannes Reinecke Reviewed-by: Christoph Hellwig Signed-off-by: Martin Wilck Signed-off-by: Jens Axboe List of files: /linux-6.15/drivers/block/swim3.c
