From bc74b4f5e63a09fb78e245794a0de1e5a2716bbe Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 9 Aug 2009 15:14:29 -0400 Subject: SUNRPC: Allow the cache_detail to specify alternative upcall mechanisms For events that are rare, such as referral DNS lookups, it makes limited sense to have a daemon constantly listening for upcalls on a channel. An alternative in those cases might simply be to run the app that fills the cache using call_usermodehelper_exec() and friends. The following patch allows the cache_detail to specify alternative upcall mechanisms for these particular cases.
