Ran -g auto xfstests on overlay over xfs+reflink.
There are no failures and no changes w.r.t skipped tests since v4.17-rc1.

ACK on w.r.t addressing my review comments.

ACK on the freeze protection fix.
Not sure if the fact that we take __mnt_want_write() on overlay and not on
upper_mnt for ovl_real_ioctl() is a problem (i.e. can upper_mnt become
readonly from under overlay? and do we care?).

Thanks,
Amir.
