CephFS Snapshots do not know up in Windows Explorer "Previous Versions" tab when vfs_ceph is enabled.

I have the following VFS modules enabled:

vfs objects = acl_xattr ceph_snapshots ceph

and in the samba logs, I always get a "Bad file descriptor" when samba tries to query the `ceph.snap.btime` extended attribute.

However when I use the `ceph_snapshots` module WITHOUT `ceph` and share a mounted CephFS path, the snapshots show up in Windows Explorer and everything works as intended.

Maybe a possible bug in vfs_ceph? Please let me know what logs and information you'd need.
