All previous linux versions had this bug : A program might misbehave because of a spurious poll(..., timeout < 0) wakeup. Could you please refine this Changelog again ? On 32bit user program, all negative timeout values should not set a timout at all, not only 0xffffffff (-1) man poll states : The timeout argument specifies an upper limit on the time for which poll() will block, in milliseconds. Specifying a negative value in timeout means an infinite timeout. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
