[PATCH 3.17-rc4 v2 0/2] trace: kdb: Bug fixes for ftdump

From: Daniel Thompson
Date: Wed Sep 24 2014 - 06:33:25 EST

This patchset makes it possible to use kdb's ftdump command without
panicing, crashing or livelocking.

Changes since v1:

* Fixed use-after-free problems in v1 by adding logic to NULL out
buffer_iter during free operations.

* Introduced a second patch to fix a live lock when trying to display
an empty trace buffer.
