block: sed-opal: keyring support for SED keys

2023-08-22T17:10:26+00:00

Extend the SED block driver so it can alternatively obtain a key from a sed-opal kernel keyring. The SED ioctls will indicate the source of the key, either directly in the ioctl data or from the keyring. This allows the use of SED commands in scripts such as udev scripts so that drives may be automatically unlocked as they become available.

block: make blkcg_punt_bio_submit optional

2023-04-17T16:01:22+00:00

Guard all the code to punt bios to a per-cgroup submission helper by a new CONFIG_BLK_CGROUP_PUNT_BIO symbol that is selected by btrfs. This way non-btrfs kernel builds don't need to have this code.

blk-mq-rdma: remove queue mapping helper for rdma devices

2023-04-13T06:59:05+00:00

No rdma device exposes its irq vectors affinity today. So the only mapping that we have left, is the default blk_mq_map_queues, which we fallback to anyways. Also fixup the only consumer of this helper (nvme-rdma). Remove this now dead code. Signed-off-by: Sagi Grimberg Acked-by: Keith Busch Signed-off-by: Christoph Hellwig

block: remove obsolete config BLOCK_COMPAT

2023-03-16T15:35:44+00:00

Before commit bdc1ddad3e5f ("compat_ioctl: block: move blkdev_compat_ioctl() into ioctl.c"), the config BLOCK_COMPAT was used to include compat_ioctl.c into the kernel build. With this commit, the code is moved into ioctl.c and included with the config COMPAT. So, since then, the config BLOCK_COMPAT has no effect and any further purpose. Remove this obsolete config BLOCK_COMPAT.

block: default BLOCK_LEGACY_AUTOLOAD to y

2022-02-27T21:49:23+00:00

As Luis reported, losetup currently doesn't properly create the loop device without this if the device node already exists because old scripts created it manually. So default to y for now and remove the aggressive removal schedule.
