Subject: VFS: Handle lazytime in do_mount()
X-Git-Tag: v4.15-rc4~7^2

VFS: Handle lazytime in do_mount()

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().
