Nonexistent CONFIG_FILE_MODE?

[Nathan Hartman]

I noticed several instances of preprocessor logic like this example
from register_driver() in fs_registerdriver.c:

#ifdef CONFIG_FILE_MODE
      node->i_mode    = mode;
#endif

But there doesn't seem to be such a Kconfig option.

Did I miss something? Or is this a remnant from a bygone era?

Thanks,
Nathan
