Subject: [PATCH 3/3] mountd: ignore use_ipaddr and just try both client types
Date: Fri, 20 Apr 2012 18:46:18 -0400	[thread overview]
Message-ID: <1334961978-2843-4-git-send-email-bfields@redhat.com> (raw)
In-Reply-To: <1334961978-2843-1-git-send-email-bfields@redhat.com>

From: "J. Bruce Fields" <bfields@redhat.com>

There are races when switching use_ipaddr on or off: it's possible the
kernel may still do export upcalls with the previous client type.  So,
let's just match either one.
