This patch makes things a little more robust by: - including to get definitions of u32, mode_t, and so on. - forward declaring struct file_operations. - including when CONFIG_DEBUG_FS is not set The last change is particularly useful, as a kernel developer is likely to build with debugfs always enabled and never see the build breakage cased if debugfs is disabled.
