Since commit57e62324e4("NFS: Store the legacy idmapper result in the keyring") nfs_idmap_cache_timeout changed units from jiffies to seconds. Unfortunately sysctl interface was not updated accordingly. As a effect updating /proc/sys/fs/nfs/idmap_cache_timeout with some value will incorrectly multiply this value by HZ. Also reading /proc/sys/fs/nfs/idmap_cache_timeout will show real value divided by HZ.
