[PATCH] rxrpc update

From: David Howells
Date: Fri Jan 16 2004 - 11:48:48 EST



Hi Andrew, Linus,

Here's a patch to fix some bugs in my RxRPC code, including the fix for the
transport initialisation failure recovery spotted by Pete Zaitcev.

It also inserts some extra spaces in a few places.

David
