From 2bd615797ef32ec06ef0ee44198a7aecc21ffd8c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 3 Jan 2006 09:55:19 +0100 Subject: [PATCH] SUNRPC: Ensure that SIGKILL will always terminate a synchronous RPC call. ...and make sure that the "intr" flag also enables SIGHUP and SIGTERM to interrupt RPC calls too (as per the Solaris implementation).
