From 5b444cc9a4c979aa0fa185c8ddca221462a34b7a Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 17 Aug 2012 21:47:53 -0400 Subject: svcrpc: remove handling of unknown errors from svc_recv svc_recv() returns only -EINTR or -EAGAIN. If we really want to worry about the case where it has a bug that causes it to return something else, we could stick a WARN() in svc_recv. But it's silly to require every caller to have all this boilerplate to handle that case. Signed-off-by: J.
