Subject: [PATCH 58/74] fallthru: ext2 support for lookup of d_type/d_ino in fallthrus
Date: Tue, 22 Mar 2011 19:04:49 -0700 [thread overview]
Message-ID: <1300845905-14433-15-git-send-email-valerie.aurora@gmail.com> (raw)
In-Reply-To: <1300845905-14433-1-git-send-email-valerie.aurora@gmail.com>
From: Valerie Aurora <vaurora@redhat.com>
Now that we have full union lookup support, lookup the true d_type and
d_ino of a fallthru.
