== SRU Justification ==
A regression was introduced when upstream 4.4 stable commit 20cbe9a3aa2 was
back ported to Xenial. The back port failed to remove a call to kfree() in
release_ds_buffer(). This was causing a kernel oops on many different systems.
This commit removes the kfree() like it should have been in the original commit.

UBUNTU: SAUCE: kaiser: fix perf crashes - fix to original commit
== Regression Potential ==
Low. This patch is fixing a current regression. It is just doing
what the original commit meant to do.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
