From: Dariusz Stojaczyk <dariuszx.stojac...@intel.com>
The doc says this function returns negative errno
on error, but it currently returns either -1 or
positive errno.
It was incorrectly assumed that pthread_setname_np()
returns negative error numbers. It always returns
positive ones, so this patch negates its return value
before returning.
