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.
