• 4c7da06f5   dm persistent data: eliminate unnecessary return values ... Browse Code »

  dm_bm_unlock and dm_tm_unlock return an integer value but the returned
  value is always 0. The calling code sometimes checks the return value
  and sometimes doesn't.

  Eliminate these unnecessary return values and also the checks for them.

• 8001e87d0   dm array: if resizing the array is a noop set the new root to the old one ... Browse Code »

  This could've been quite bad (to return success but not update the new
  root to point at the old) but in practice the only known consumer of the
  dm array code is the DM cache target. And the DM cache target passes in
  the same old root to array_resize() anyway.

• ed9571f0c   dm array: fix a reference counting bug in shadow_ablock ... Browse Code »

  An old array block could have its reference count decremented below
  zero when it is being replaced in the btree by a new array block.

  The fix is to increment the old ablock's reference count just before
  inserting a new ablock into the btree.
