[PATCH v4 0/3] block: show crypto capabilities in sysfs

From: Eric Biggers
Date: Mon Jan 24 2022 - 19:16:25 EST


This series adds sysfs files that expose the inline encryption
capabilities of request queues.

Patches 1 and 2 are some related cleanups for existing blk-sysfs code.
Patch 3 is the real change; see there for more details.

This series applies to v5.17-rc1.

Changed v3 => v4:
- Reworded a comment in patch 2.
- Updated dates in sysfs documentation.
- Added more Reviewed-by tags.

Changed v2 => v3:
- Moved the documentation into Documentation/ABI/stable/sysfs-block,
and improved it a bit.
- Write "/sys/block/" instead of "/sys/class/block/".
- Added Reviewed-by tags.

Changed v1 => v2:
- Use sysfs_emit() instead of sprintf().
- Use __ATTR_RO().

Eric Biggers (3):
block: simplify calling convention of elv_unregister_queue()
block: don't delete queue kobject before its children
blk-crypto: show crypto capabilities in sysfs
