Greg, please add mainline d7ee9469 ("VFS: Handle lazytime in do_mount()") to 4.14. It fixes a regression in 4.14 where the lazytime mount option got lost in a code reshuffling and mounting with -o lazytime no longer works. After moving to 4.14 I noticed that lazytime mounts had gone, and that patch fixes it. It applies cleanly. thanks, Holger
