• 3d745ea5b   block: simplify queue allocation ... Browse Code »

  Current make_request based drivers use either blk_alloc_queue_node or
  blk_alloc_queue to allocate a queue, and then set up the make_request_fn
  function pointer and a few parameters using the blk_queue_make_request
  helper. Simplify this by passing the make_request pointer to
  blk_alloc_queue, and while at it merge the _node variant into the main
  helper by always passing a node_id, and remove the superfluous gfp_mask
  parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case.

• fef912bf8   block: genhd: add 'groups' argument to device_add_disk ... Browse Code »

  Update device_add_disk() to take an 'groups' argument so that
  individual drivers can register a device with additional sysfs
  attributes.
  This avoids race condition the driver would otherwise have if these
  groups were to be created with sysfs_add_groups().

• 8b904b5b6   block: Use blk_queue_flag_*() in drivers instead of queue_flag_*() ... Browse Code »

  This patch has been generated as follows:

  for verb in set_unlocked clear_unlocked set clear; do
  replace-in-files queue_flag_${verb} blk_queue_flag_${verb%_unlocked} \
  $(git grep -lw queue_flag_${verb} drivers block/bsg*)
  done

  Except for protecting all queue flag changes with the queue lock
  this patch does not change any functionality.

• 3ffb0ba9b   libnvdimm, {btt, blk}: do integrity setup before add_disk() ... Browse Code »

  Prior to 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk")
  we needed to temporarily add a zero-capacity disk before registering for
  blk-integrity. But adding a zero-capacity disk caused the partition
  table scanning to bail early, and this resulted in partitions not coming
  up after a probe of the BTT or blk namespaces.

  We can now register for integrity before the disk has been added, and
  this fixes the rescan problems.
