Subject: [PATCH 0/2] perf/x86/intel/bts: Small fixes
Date: Thu, 5 Dec 2019 17:28:51 +0300 [thread overview]
Message-ID: <20191205142853.28894-1-alexander.shishkin@linux.intel.com> (raw)
Hi Peter and Ingo,
Here are two small fixes that resulted from running perf_fuzzer on a !KPTI
kernel. One is a misguided and unannotated warning and another is a sketchy
use of page_private(). The choice between deleting the BTS driver and
fixing it is not obvious, though. It may theoretically still have users.
