Subject: Linux-1.3.67 - NFS caching

I just made a 1.3.67 available, which fixes some of the problems people
have had (the old SLIP and IP masquerading patches). It also does

 - fix recursion leading to stack overflow in get_more_buffer_heads()
 - NFS client read cache integrated with the generic buffer cache (whee.
   Speed improvements like you wouldn't believe for cached reads).
 - INET socket close code re-organized, hopefully the TCP sockets in
   state CLOSE really will go away now
 - nanosleep() system call

Now, I'm most interested to hear about the TCP_CLOSE bug (is it really
gone?) and about NFS experiences. Linux used to be pretty bad at NFS
caching, with a rather small and anemic packet cache that really didn't
do much for you, and now when NFS uses the normal buffer cache it's a
rather agressive cacher. What say you, all heavy NFS users?
