Btw, I don't think the name is the primary problem, as we seem to
disagree even about the problem space.  The current patch series
from Jeff helps with the stable handle problem, which is an important
one, although maybe not the one you and Amir care about most.  I care
about it most, because the addition of unstable handles caused problems
and I really want that fixed before it spreads further, and I think
anything mentioning NFS in that is factually wrong.  If we need
additional flags to work around other issues (as in the list compiled
by Neil) I'd still prefer them to be named about what issues they
deal with, but folks get too tired of that I could probably with a
"NFSD get the f^&&& out" name if we'd just keep shouting at each
other otherwise.
