+From 1a000636c1828eecdcec5360a51623ef4ffbff04 Mon Sep 17 00:00:00 2001
+From: Beniamin Sandu <beniaminsandu@gmail.com>

+Subject: trace-cmd: make it build against musl C library
+
+* add some missing headers and macros
+* set pthread affinity using pthread_setaffinity_np after creating the thread
+instead of pthread_attr_setaffinity_np (which seems to not be implemented
+in musl)
+
+Tested using https://musl.cc/x86_64-linux-musl-native.tgz
+
