Merge branch 'for-6.11/block-limits' into for-6.11/block

Browse Source 
Merge in queue limits cleanups.

* for-6.11/block-limits:
  block: move the raid_partial_stripes_expensive flag into the features field
  block: remove the discard_alignment flag
  block: move the misaligned flag into the features field
  block: renumber and rename the cache disabled flag
  block: fix spelling and grammar for in writeback_cache_control.rst
  block: remove the unused blk_bounce enum
