The tile architecture already marks RO_DATA as read-only in the kernel, so grouping RO_AFTER_INIT_DATA with RO_DATA, as is done by default, means the kernel faults in init when it tries to write to RO_AFTER_INIT_DATA. For now, just arrange that __ro_after_init is handled like __write_once, i.e. __read_mostly. Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Chris Metcalf <cmetcalf@mellanox.com> |
