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
|
|
|
