Yes. Synchronous RPC calls should never be run by rpciod. This is a known problem, and I'm working on a fix. I've already got working code for nfs4_do_close(), but a similar scheme has be set up for the byte range locking code. At the moment I'm busy with my move from Norway to the US, so please give me a week or 2 to get back to you on this one. Cheers, Trond
