| Subject: fs/dcache: avoid unused-function warning |
| |
| 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. |
