I replied to Michael, but missed to address the list. Jakubs 
interpretation is right. See my response below.


Hello!

Sorry, there is a typo on my side, and I have been less specific then 
desirable.

The problem is there:

static inline void
wrpkru(unsigned int pkru) ... <== returns void
...
int
pkey_set(int pkey, unsigned long rights, unsigned long flags) <== 
returns int
{
unsigned int pkru = (rights << (2 * pkey));
return wrpkru(pkru); <== here the V O I D I S R E T U R N E D A S I N T
}

Regards, Aaron
