From 5e113224c17e2fb156b785ddbbc48a0209fddb0c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 2 Sep 2019 13:02:55 -0400 Subject: nfsd: nfsd_file cache entries should be per net namespace Ensure that we can safely clear out the file cache entries when the nfs server is shut down on a container. Otherwise, the file cache may end up pinning the mounts. Signed-off-by: Trond Myklebust Signed-off-by: J.
