Sure. I have written a check to test for kfree and brelse of ERR_PTRs. I'll test it today. Hm...

I'll look into it. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe smatch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
