Subject: [PATCH v2 07/15] xfs: mount-api - refactor xfs_fs_fill_super()
Date: Fri, 23 Aug 2019 08:59:54 +0800 [thread overview]
Message-ID: <156652199438.2607.11044864070510345078.stgit@fedora-28> (raw)
In-Reply-To: <156652158924.2607.14608448087216437699.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.
