[PATCH RFC] SUNPRC: remove marking service temporary sockets with XPT_CHNGBUF

From: Stanislav Kinsbursky <hidden>
Date: 2012-01-20 12:55:59

This is a cleanup patch.
Service temporary sockets can be TCP or RDMA only. But XPT_CHNGBUF service
socket flag is checked only for UDP sockets on receive.
Thus (if I don't miss something non-obvious) this bit raising for temporary
sockets can be removed.

I'm assuming that Bruce will prefer to carry this, since it is
completely orthogonal to the net namespace patchsets.

Yes, I believe that's correct, it's leftover cleanup from
9660439861aa8dbd5e2b8087f33e20760c2c9afc "svcrpc: take advantage of tcp
autotuning".

I'll ignore the "RFC" marking and apply unless you tell me otherwise....
