The purpose of the constant it is not entirely clear from its name.

As this constant is going to be exposed in a UAPI header, give it a more
specific name for clarity. As all its users call it 'marker', use that
wording in the constant itself.

module: Fix prefix for module.sig_enforce module param 2022-06-02T19:44:33+00:00 Saravana Kannan saravanak@google.com 2022-06-02T03:56:52+00:00 73503963b715a64a44aa2b1c486114b917a17c73 Commit cfc1d277891e ("module: Move all into module/") changed the prefix of the module param by moving/renaming files. A later commit also moves the module_param() into a different file, thereby changing the prefix yet again. This would break kernel cmdline compatibility and also userspace compatibility at /sys/module/module/parameters/sig_enforce. So, set the prefix back to "module.".
