Subject: [PATCH 2/3] nfs: simplify two-level sysctl registration for nfs4_cb_sysctls
Date:   Fri, 10 Mar 2023 14:58:41 -0800
Message-Id: <20230310225842.3946871-3-mcgrof@kernel.org>

Precedence: bulk

There is no need to declare two tables to just create directories,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
