From: "Ken'ichi Ohmichi" [1/3] Cleanup the coding style according to Andrew's comments: http://lists.infradead.org/pipermail/kexec/2007-August/000522.html - vmcoreinfo_append_str() should have suitable __attribute__s so that the compiler can check its use. - vmcoreinfo_max_size should have size_t. - Use get_seconds() instead of xtime.tv_sec. - Use init_uts_ns.name.release instead of UTS_RELEASE.
