Subject: [PATCH 0/4] selftests/livepatch: rework of test-klp-{callbacks,shadow_vars}
Date: Thu, 28 May 2020 09:48:45 -0400
Message-ID: <20200528134849.7890-1-ycote@redhat.com> (raw)

The test-klp-callbacks change implement a synchronization replacement of
initial code to use completion variables instead of delays. The
completion variable interlocks the busy module with the concurrent
loading of the target livepatch patches which works with the execution
flow instead of estimated time delays.

The test-klp-shadow-vars changes first refactors the code to be more of
a readable example as well as continuing to verify the component code.
The patch is broken in two to display the renaming and restructuring in
part 1 and the addition and change of logic in part 2. The last change
frees memory before bailing in case of errors.

Patchset to be merged via the livepatching tree is against: livepatching/for-next
