Subject: [PATCH RESEND 3.18-rc3 v2 0/2] trace: kdb: Bug fixes for ftdump
Date: Thu, 6 Nov 2014 12:41:54 +0000 [thread overview]
Message-ID: <1415277716-19419-1-git-send-email-daniel.thompson@linaro.org> (raw)
In-Reply-To: <1411554781-16751-1-git-send-email-daniel.thompson@linaro.org>
This patchset makes it possible to use kdb's ftdump command without
panicing, crashing or livelocking. The ftdump command cannot be used
at all without these changes.
IIRC this patches are still pending Jason's ack.
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.
