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;

But there doesn't seem to be such a Kconfig option.
Did I miss something? Or is this a remnant from a bygone era?
No, it was intended to be a placeholder for future support. These
security-related features will be needed someday, but they are not
used today (or even fully implemented). This conditions out logic
that depends on user and group privileges.
No harm in removing code conditioned on CONFIG_FILE_MODE other than we
will have to restore it someday.
