    dm verity: fix require_signatures module_param permissions · 0c1f3193
    John Keeping authored
    The third parameter of module_param() is permissions for the sysfs node
    but it looks like it is being used as the initial value of the parameter
    here.  In fact, false here equates to omitting the file from sysfs and
    does not affect the value of require_signatures.
    Making the parameter writable is not simple because going from
    false->true is fine but it should not be possible to remove the
    requirement to verify a signature.  But it can be useful to inspect the
    value of this parameter from userspace, so change the permissions to
    make a read-only file in sysfs.
