Right,
here are some patches to the sunrpc code in should apply against
2.2.0pre4, these patches allow NFS over TCP ro mounts to work a lot more
resiliantly,
before these patches I could crash it with
mount -t nfs -o tcp,nolock oak:/foo /foo
cd /foo
find .
the find would stop and the rpc system would get stuck waiting for the tcp
dispatcher to wake up (which it would never do)...
with these patches I can now do multiple finds and du and file reads with
no problems, I'm looking into the file writing problem Alan mentioned now
(whenever my flu goes away)....
the diff is in 3 parts, the first piece to linux/net/sunrpc/sched.c is
most important, the next piece to xprt.c also seems to help as it ensures
that the xprt is on the rpc_xprt_pending list before waking the
tcp_dispatcher, and the fix to linux/include/linux/xprt.h just seems right
to me ...
Comments anyone please test ..
Dave.
