Subject: [regression] sched_getaffinity fails with EINVAL in 2.6.31-rc4
Date: Mon, 27 Jul 2009 13:16:12 -0400	[thread overview]
Message-ID: <4A6DE0DC.2070207@gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 485 bytes --]

I am not sure when this started, but noticed that sched_getaffinity is
not working in -rc4.

[pid  6254] sched_getaffinity(0, 128, 0x7f80586b1fe0) = -1 EINVAL
(Invalid argument)

Here is a simple program for reproduction:

#include <sched.h>

int main(void)
{
	cpu_set_t mask;
	int ret;

	ret = sched_getaffinity(0, sizeof(mask), &mask);
	if (ret < 0)
		perror("getaffinity");

	return ret;
}

If I get time, I will bisect this later today.

Regards,
-Greg
