Subject: SUNRPC: Ensure xprt_connect_status handles all potential connection errors
X-Git-Tag: v3.14-rc1~15^2~32
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fe8d04e8c3a1eb49089793e38b60a17cee564e3;p=profile%2Fcommon%2Fkernel-common.git

SUNRPC: Ensure xprt_connect_status handles all potential connection errors

Currently, xprt_connect_status will convert connection error values such
as ECONNREFUSED, ECONNRESET, ... into EIO, which means that they never
get handled.
