[PATCH 1/2] misc: Set generic pselect as ENOSYS

[Lukasz Majewski]

Dear Adhemerval,

> +__pselect (int nfds, fd_set *readfds, fd_set *writefds, fd_set
> *exceptfds,
> +	   const struct timespec *timeout, const sigset_t *sigmask)
> +{
> +  int ret = __pselect_syscall (nfds, readfds, writefds, exceptfds,
> timeout,
> +			       sigmask);
> +  if (ret < 0 && errno != ENOSYS)
> +    return ret;

Is the above condition correct?

The pselect returns -1 on error or >= 0 on success.

Shouldn't it be instead:

if (! (ret == -1 && errno == ENOSYS))

Only when pselect is not supported we shall fallback to select based
implementation.


Best regards,

Lukasz Majewski
