--b.

----------------------------------------------------------------
Highlights:

	- add a new knfsd file cache, so that we don't have to open and
	  close on each (NFSv2/v3) READ or WRITE.  This can speed up
	  read and write in some cases.  It also replaces our readahead
	  cache.
	- Prevent silent data loss on write errors, by treating write
	  errors like server reboots for the purposes of write caching,
	  thus forcing clients to resend their writes.
	- Tweak the code that allocates sessions to be more forgiving,
	  so that NFSv4.1 mounts are less likely to hang when a server
	  already has a lot of clients.
	- Eliminate an arbitrary limit on NFSv4 ACL sizes; they should
	  now be limited only by the backend filesystem and the
	  maximum RPC size.
	- Allow the server to enforce use of the correct kerberos
	  credentials when a client reclaims state after a reboot.

And some miscellaneous smaller bugfixes and cleanup.
