Subject[PATCH 1/2] fs/inode: avoid unused-variable warning
Date
From: Arnd Bergmann <arnd@arndb.de>

Now that 'inodes_stat' is marked 'static', it causes a harmless warning
whenever it is unused:

fs/inode.c:73:29: error: 'inodes_stat' defined but not used [-Werror=unused-variable]
73 | static struct inodes_stat_t inodes_stat;

Move it into the #ifdef that guards its only references.

Fixes: 245314851782 ("fs: move inode sysctls to its own file")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
