I've submitted the ceph.snap.btime vxattr changes along with basic
test coverage via:
https://github.com/ceph/ceph/pull/27077

Feedback appreciated :)

As you indicated, Sage, Kernel CEPHFS_FEATURE_REPLY_ENCODING support
looks like a pretty big chunk of work, so I'll put it on the back-burner
for now until I'm at least all done with the corresponding Samba
changes.

Cheers, David
