[Qemu-stable] [PATCH 0/2] Active commit regression fix

[Jeff Cody]

Bug #1300209 is a regression in 2.5, introduced during the 
change away from bdrv_swap().

When we change the parent backing link (change_parent_backing_link),
we must also accomodate non-NULL tqe_prev pointers that point to a
NULL entry.  Please see patch #1 for more details.

Jeff Cody (2):
  block: change parent backing link when *tqe_prev == NULL
