samba - Jan 2020 - filesystems with xattr size suitable for use with vfs_fruit

Hi all,
   I'm looking into using fruit:resource = xattr to be rid of 
._AppleDouble files.  (Currently I have fruit:resource = file)
   man smb.conf mentions ZFS .  Is this the only filesystem which would 
work?
   E.g. the page below does not mention a size limit for cephfs, but 
says that they are stored in a key/value database.

Thanks!
Chad.
