Sorry, I'm still catching up after being on vacation.  There is a
batch of commits which I've reviewed (up to May 17th) which is
currently undergoing testing.  So that doesn't include this patch yet,
but it's on the list of patches to be reviewed at
patchworks.ozlabs.org/project/linux-ext4 so it won't fall through the
cracks.
