Subject: [PATCH 1/5] xfs: move xfs_dir2_addname()
Date: Thu, 25 Oct 2018 09:57:12 +1100	[thread overview]
Message-ID: <20181024225716.19459-2-david@fromorbit.com> (raw)
In-Reply-To: <20181024225716.19459-1-david@fromorbit.com>

From: Dave Chinner <dchinner@redhat.com>

This gets rid of the need for a forward  declaration of the static
function xfs_dir2_addname_int() and readies the code for factoring
of xfs_dir2_addname_int().

Signed-off-by: Dave Chinner <dchinner@redhat.com>
