Subject: [PATCH 03/10] tun: Use POLLERR not EBADF in tun_chr_poll
Date: Tue, 20 Jan 2009 12:59:05 -0800	[thread overview]
Message-ID: <m1hc3tlmna.fsf_-_@fess.ebiederm.org> (raw)
In-Reply-To: <m1mydllmpf.fsf_-_@fess.ebiederm.org> (Eric W. Biederman's message of "Tue\, 20 Jan 2009 12\:57\:48 -0800")


EBADF is meaningless in the context of a poll mask so use POLLERR
instead.
