From 9f9d2ebe693a98d517257e1a39f61120b4473b96 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 17 Aug 2012 21:35:24 -0400 Subject: svcrpc: make xpo_recvfrom return only >=0 The only errors returned from xpo_recvfrom have been -EAGAIN and -EAFNOSUPPORT. The latter was removed by a previous patch. That leaves only -EAGAIN, which is treated just like 0 by the caller (svc_recv). So, just ditch -EAGAIN and return 0 instead. Signed-off-by: J.
