From 52c4044d00fe703eb3fb18e0d8dfd1c196eb28be Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 11 Jan 2008 17:09:44 -0500 Subject: NLM: Introduce external nlm_host set-up and tear-down functions We would like to remove the per-lock-operation nlm_lookup_host() call from nlmclnt_proc(). The new architecture pins an nlm_host structure to each NFS client superblock that has the "lock" mount option set. The NFS client passes in the pinned nlm_host structure during each call to nlmclnt_proc(). NFS client unmount processing "puts" the nlm_host so it can be garbage- collected later. This patch introduces externally callable NLM functions that handle mount-time nlm_host set up and tear-down.
