From fd3f518fc1140622e752ac51d0ff18bb74f1d180 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Wed, 9 Nov 2022 10:49:12 -0800 Subject: [PATCH] perf thread_map: Reduce exposure of libperf internal API Remove unnecessary include of internal threadmap.h and refcount.h in thread_map.h. Switch to using public APIs when possible or including the internal header file in the C file. Fix a transitive dependency in openat-syscall.c broken by the clean up.
