From bda9cac1db8ab044e9edbfe5730283016b67d451 Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Thu, 6 Dec 2012 14:23:29 +0300 Subject: [PATCH] nfsd: introduce helpers for generic resources init and shutdown NFSd have per-net resources and resources, used globally. Let's move generic resources init and shutdown to separated functions since they are going to be allocated on first NFSd service start and destroyed after last NFSd service shutdown.
