Subject: [Qemu-devel] [PATCH 0/2] Active commit regression fix
Date: Sat, 30 Jan 2016 00:17:47 -0500 [thread overview]
Message-ID: <cover.1454129966.git.jcody@redhat.com> (raw)
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.
