When CONFIG_CIFS_DEBUG2 is disabled, the only reference to this
function is hidden, causing a harmless warning:
fs/smb/client/cifs_debug.c:395:30: error: 'cifs_debug_dirs_proc_ops' defined but not used [-Werror=unused-const-variable=]
395 | static const struct proc_ops cifs_debug_dirs_proc_ops = {
| ^~~~~~~~~~~~~~~~~~~~~~~~
Make the #ifdef checks around them consistent by always using
the DEBUG2 variant.
Fixes: 63bff18d4aa0 ("smb: client: fix (remove) drop_dir_cache module parameter")
Thanks for catching that.
I sent v2/v3 of that patch changing the dependency from
CONFIG_CIFS_DEBUG2 to CONFIG_CIFS_DEBUG, can you adjust to the
latter please?
Cheers,
