Cover letter [PATCH 0/2] tracing: hist trigger KASAN fixes
Dmitry Vyukov found and reported an issue with hist triggers when running the hist trigger selftests, which Steve Rostedt sent a patch for and which fixed part of the problem; I copied his patch to fix another similar problem in the same code. The result is the first patch in this series.
After that fix was applied, another problem appeared, again triggered by the selftests. The second patch here fixes that.
I then ran my exhaustive testsuite with KASAN enabled and didn't find anything else beyond those.
