Subject: [PATCH] VFS: Handle lazytime in do_mount()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

commit d7ee946942bdd12394809305e3df05aa4c8b7b8f upstream.

Since commit e462ec50cb5fa ("VFS: Differentiate mount flags (MS_*) from
internal superblock flags") the lazytime mount option doesn't get passed
on anymore.

Fix the issue by handling the option in do_mount().
