freebsd stable - Feb 2006 - rpc.lockd brokenness

Hi,

Since I committed rev 1.18 of usr.sbin/rpc.lockd/lock_proc.c, I heard
several report about interoperability problems.

Unfortunatelly, I cannot reproduce this problem.  Relevant PRs are:

http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/80389
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/84953

My questions are:

- Problem is uninterruptible lock?  Or other problem exists?
- If you have a problem, that is reproducable?  Or sometimes happens?
- If you have a problem, backing out r1.18 of my commit solves it?

I hope I can fix this problem before 6.1R.  Any help will be
appreciated.

BTW, the kernel->user protocol for rpc.lockd on the client currently cannot 
support lock request aborts, so the sleep waiting on locks has to remain 
uninterruptible until that is fixed.
