Let's get this into -next so we can see whether this leads to any
performance or other regressions. It's moved to a vfs.unstable.* branch
for now. If nothing bad happens it'll be upgraded to a vfs.* branch.
Filesystems that prefer to carry their fs specific patch themselves can
request a stable tag for the generic changes.

---

Applied to the vfs.unstable.ctime branch of the vfs/vfs.git tree.
Patches in the vfs.unstable.ctime branch should appear in linux-next soon.

Please report any outstanding bugs that were missed during review in a
new review to the original patch series allowing us to drop it.

It's encouraged to provide Acked-bys and Reviewed-bys even though the
patch has now been applied. If possible patch trailers will be updated.
