Anyway, better be conservative than sorry - I think we want to switch to
"fsid" approach to avoid messing with these networking issues, including
IPV6 modification. That is, we use fsid as the key to drop the lock and
set per-fsid NLM grace period. The ha-callout will have a 4th argument
(fsid) when invoked.
