| Dummy pthread_setaffinity_np() when not available |
| |
| On uClibc configurations that do not use the NPTL thread |
| implementation, pthread_setaffinity_np() is not available. This patch |
| defines a dummy (empty) implementation of this function for such |
| cases. |
| |
| The only few architectures that do not provide the NPTL thread |
| implementation are very likely to be non-SMP architectures, and |
| therefore, setting the affinity of the thread is not doing anything |
| useful, so having an empty stub for pthread_setaffinity_np() is not a |
| problem. |
