Yeah, the mixup in the buffer cache is going to cause us problems, and
doesn't look like something we want to attempt for 5.2-RELEASE. I think
there are two work-arounds we should put in place though:
(1) Return EOPNOTSUPP if you try an EA operation on a UFS specfs node.
(2) Suggest firmly that people use devfs; symlink from the Linux /dev to
the FreeBSD/dev, or mount a new devfs instance for Linux.
While there might not be time before 5.2-RELEASE, the Linux compat stuff
needs to recognize a devfs system and not use hard-coded devices -- that
will break more and more as we move away from device numbers.
I'm tesitng a patch for (1) and will send it out this evening for review.
