Subject: [PATCH urgent 0/2] x86/unwind: an unwinder fix and debugging improvement
Date: Fri, 16 Dec 2016 10:05:04 -0600 [thread overview]
Message-ID: <cover.1481904011.git.jpoimboe@redhat.com> (raw)
Patch 1 is a fix for an unwinder issue found by Boris. Patch 2 is a
debugging improvement which helped diagnose the problem.
Patch 1 needs to go into tip/urgent for 4.10. I'd argue that patch 2
should also go into urgent because it only affects the error path and it
makes the new unwinder warnings much more useful.
