Subject: [PATCH 2/2] fs/dcache: avoid unused-function warning
Date: Fri, 3 Dec 2021 20:01:02 +0100 [thread overview]
Message-ID: <20211203190123.874239-2-arnd@kernel.org> (raw)
In-Reply-To: <20211203190123.874239-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Now that 'dentry_stat' is marked 'static', we can run into this warning:
fs/dcache.c:128:29: error: 'dentry_stat' defined but not used [-Werror=unused-variable]
128 | static struct dentry_stat_t dentry_stat = {
Hide it in the same #ifdef as its only references.
Fixes: f0eea17ca8da ("fs: move dcache sysctls to its own file")
