[PATCH 0/2] perf, bts: Make BTS exclusive again

[Alexander Shishkin <alexander.shishkin@linux.intel.com>]

Hi Peter,

While looking at something else I noticed that the exclusive event
filter only allows one such event per context, whereas it should allow
one such event from each PMU that has PERF_PMU_CAP_EXCLUSIVE. At the
same time, intel_bts PMU doesn't even have this capability set (which
is why on systems that allow coexistance of PT and BTS it still works,
see ccbebba4c6 for more context).
