The PERF_COUNT_SW_BPF_OUTPUT entry is missing in the event_symbols_sw
array. Due to that "perf list sw" segfaults, because a NULL pointer
is passed to strlen() function at util/parse-events.c:1895.
After this patch, the syms array is set correctly, so "perf list sw"
does not segfault.
Before:
Segmentation fault
After:
