Bruce Fields" <bfields@...ldses.org>, Trond Myklebust <Trond.Myklebust@...app.com>, "David S. Miller" <davem@...emloft.net>, Mika Westerberg <mika.westerberg@...ux.intel.com>, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] nfsd: fix compile warning about unused variable 'nn' Commit c9a4962881 (nfsd: make client_lock per net) added lockdep_assert_held() call to function free_client(). However, if lockdep is disabled we get following compiler warning: fs/nfsd/nfs4state.c: In function ‘free_client’: fs/nfsd/nfs4state.c:1051:19: warning: unused variable ‘nn’ [-Wunused-variable] Fix this by marking the 'nn' with __maybe_unused.
