Subject: [PATCH 3.17-rc4 v2 0/2] trace: kdb: Bug fixes for ftdump
Date: Wed, 24 Sep 2014 11:32:59 +0100 [thread overview]
Message-ID: <1411554781-16751-1-git-send-email-daniel.thompson@linaro.org> (raw)
In-Reply-To: <1410360247-13791-1-git-send-email-daniel.thompson@linaro.org>
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.
