From 33d90ac0581ce81d1ebfc51918a2757e41a6011c Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 11 Apr 2013 15:06:36 -0400 Subject: [PATCH] SUNRPC: allow disabling idle timeout In the gss-proxy case we don't want to have to reconnect at random--we want to connect only on gss-proxy startup when we can steal gss-proxy's context to do the connect in the right namespace. So, provide a flag that allows the rpc_create caller to turn off the idle timeout. Signed-off-by: J.
