Subject: [PATCH v8 0/4] make logical block size configurable

From: Li Nan <linan122@...wei.com>

v8:
 - Path 2: remove unnecessary bioset_initialized() check.
 - Path 3: remove the max(blksize, ...)
 - Path 4: set MD_SB_CHANGE_DEVS instead of call md_update_sb().

v7:
 - Add three prerequisite patch to fix some config lbs related issues
 - Update sb when lbs configuration is done
 - This feature should support raid0, update documentation accordingly

Li Nan (4):
  md: delete md_redundancy_group when array is becoming inactive
  md: init bioset in mddev_init
  md/raid0: Move queue limit setup before r0conf initialization
  md: allow configuring logical block size
