This patchset is the userspace portion of the knfsd client name tracking
overhaul. See this patch series for an explanation:
nfsd: overhaul the client name tracking code
The main changes from the last set are:
- the daemon will now reopen the pipe if it's deleted and recreated. This
can happen if knfsd is restarted.
- The daemon now implements an "init" upcall. When knfsd starts, it will
upcall to userspace to ask for a "boot_generation" value. nfsdcld will
fetch that value out of the DB, increment it and reinsert it (atomically).
That guarantees uniqueness of the boot generation value even when multiple
machines are sharing the same nfsdcld db.
- the "create" and "check" upcalls now send the rowid of the record in the
downcall. Eventually the kernel will use this to track some info about
lockowners in some situations. For now the kernel ignores this value,
but the daemon passes it anyway.
- "remove" functionality has been removed from the daemon. The upcall that
previously requested that has been removed, so we have no need for that
functionality in the daemon. Client records are now only removed when
the grace period ends.
