From b72679ee89a0a0ecd26f7b6fcae96cdaababff94 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 18 Aug 2019 14:18:46 -0400 Subject: notify: export symbols for use by the knfsd file cache The knfsd file cache will need to detect when files are unlinked, so that it can close the associated cached files. Export a minimal set of notifier functions to allow it to do so. Signed-off-by: Trond Myklebust Signed-off-by: Trond Myklebust Signed-off-by: J.
