• b4a1278c7   badblocks: badblocks_set/clear update unacked_exist ... Browse Code »

  When bandblocks_set acknowledges a range or badblocks_clear a range,
  it's possible all badblocks are acknowledged. We should update
  unacked_exist if this occurs.

• 1fa9ce8d0   badblocks: fix overlapping check for clearing ... Browse Code »

  Current bad block clear implementation assumes the range to clear
  overlaps with at least one bad block already stored. If given range to
  clear precedes first bad block in a list, the first entry is incorrectly
  updated.

  Check not only if stored block end is past clear block end but also if
  stored block start is before clear block end.

• 16263ff6c   block, badblocks: introduce devm_init_badblocks ... Browse Code »

  Provide a devres interface for initializing a badblocks instance. The
  pmem driver has several scenarios where it will be beneficial to have
  this structure automatically freed when the device is disabled / fails
  probe.

• 20a308f09   block: clarify badblocks lifetime ... Browse Code »

  The badblocks list attached to a gendisk is allocated by the driver
  which equates to the driver owning the lifetime of the object. Do not
  automatically free it in del_gendisk(). This is in preparation for
  expanding the use of badblocks in libnvdimm drivers and introducing
  devm_init_badblocks().

  For symmetry with badblocks_init() make it clear that this path only
  destroys incremental allocations of a badblocks instance, and does not
  free the badblocks instance itself.

• 9e0e252a0   badblocks: Add core badblock management code ... Browse Code »

  Take the core badblocks implementation from md, and make it generally
  available. This follows the same style as kernel implementations of
  linked lists, rb-trees etc, where you can have a structure that can be
  embedded anywhere, and accessor functions to manipulate the data.

  The only changes in this copy of the code are ones to generalize
  function/variable names from md-specific ones. Also add init and free
  functions.
