perf trace: Free malloc'd trace fields on exit
ASan reports several memory leaks running: # perf test "88: Check open filename arg using perf trace + vfs_getname" The first of these leaks is related to struct trace fields never being deallocated. This patch adds the function trace__exit, which is called at the end of cmd_trace, replacing the existing deallocation, which is now moved inside the new function. This function deallocates: - ev_qualifier - ev_qualifier_ids.entries - syscalls.table - sctbl - perfconfig_events Signed-off-by:Riccardo Mancini <rickyman7@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/de5945ed5c0cb882cbfa3268567d0bff460ff016.1626343282.git.rickyman7@gmail.com [ Removed needless initialization to zero, missing named initializers are zeroed by the compiler ] Signed-off-by:
