From bc591ccff27e6a85d3a0d6fcb16cfadcc45267a8 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 2 Oct 2006 02:17:44 -0700 Subject: [PATCH] knfsd: add a callback for when last rpc thread finishes nfsd has some cleanup that it wants to do when the last thread exits, and there will shortly be some more. So collect this all into one place and define a callback for an rpc service to call when the service is about to be destroyed.
