From 6f5133652eaab6fbd88bdb1b1fd2236fd82583cb Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Tue, 31 Jan 2012 14:09:00 +0400 Subject: [PATCH] SUNRPC: clear svc pools lists helper introduced This patch moves removing of service transport from it's pools ready lists to separated function. Also this clear is now done with list_for_each_entry_safe() helper. This is a precursor patch, which would be usefull with service shutdown in network namespace context, introduced later in the series.
