* fix return value of pthread_getaffinity_np and pthread_setaffinity_npRich Felker2015-03-301-8/+11
| | | | | | | these functions are expected to return an error code rather than setting errno and returning -1. (cherry picked from commit 66140b0c926ed097f2cb7474863523e4af351f5b)
* fix uninitialized output from sched_getaffinityRich Felker2015-03-301-1/+5
| | | | | | | | | the sched_getaffinity syscall only fills a cpu set up to the set size used/supported by the kernel. the rest is left untouched and userspace is responsible for zero-filling it based on the return value of the syscall. (cherry picked from commit a56e339419c1a90f8a85f86621f3c73945e07b23)
