Message

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 applies to linux-block/for-next.

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
