Subject: [PATCH v5 09/17] xfs: mount-api - refactor xfs_fs_fill_super()
Date: Wed, 09 Oct 2019 19:30:58 +0800 [thread overview]
Message-ID: <157062065791.32346.8183392339697088078.stgit@fedora-28> (raw)
In-Reply-To: <157062043952.32346.977737248061083292.stgit@fedora-28>
Much of the code in xfs_fs_fill_super() will be used by the fill super
function of the new mount-api.
So refactor the common code into a helper in an attempt to show what's
actually changed.
