References: <46E9F6A9.8060500@mxs.nes.nec.co.jp> In-Reply-To: <46E9F6A9.8060500@mxs.nes.nec.co.jp> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2259 Lines: 63 [2/4] Add nodemask_t's size and NR_FREE_PAGES's value to vmcoreinfo_data. The dump filetering command 'makedumpfile'(v1.1.6 or before) had assumed the above values, and it was not good from the reliability viewpoint. So makedumpfile v1.2.0 came to need these values and I created the patch to let the kernel output them. makedumpfile site: https://sourceforge.net/projects/makedumpfile/ Thanks Ken'ichi Ohmichi --- Signed-off-by: Ken'ichi Ohmichi --- diff -rpuN a/include/linux/kexec.h b/include/linux/kexec.h --- a/include/linux/kexec.h 2007-09-10 23:28:42.000000000 +0900 +++ b/include/linux/kexec.h 2007-09-10 23:29:52.000000000 +0900 @@ -132,11 +132,16 @@ unsigned long paddr_vmcoreinfo_note(void #define SIZE(name) \ vmcoreinfo_append_str("SIZE(%s)=%lu\n", #name, \ (unsigned long)sizeof(struct name)) +#define TYPEDEF_SIZE(name) \ + vmcoreinfo_append_str("SIZE(%s)=%lu\n", #name, \ + (unsigned long)sizeof(name)) #define OFFSET(name, field) \ vmcoreinfo_append_str("OFFSET(%s.%s)=%lu\n", #name, #field, \ (unsigned long)&(((struct name *)0)->field)) #define LENGTH(name, value) \ vmcoreinfo_append_str("LENGTH(%s)=%lu\n", #name, (unsigned long)value) +#define NUMBER(name) \ + vmcoreinfo_append_str("NUMBER(%s)=%ld\n", #name, (long)name) #define CONFIG(name) \ vmcoreinfo_append_str("CONFIG_%s=y\n", #name) diff -rpuN a/kernel/kexec.c b/kernel/kexec.c --- a/kernel/kexec.c 2007-09-10 23:28:42.000000000 +0900 +++ b/kernel/kexec.c 2007-09-10 23:29:02.000000000 +0900 @@ -1218,6 +1218,7 @@ static int __init crash_save_vmcoreinfo_ SIZE(zone); SIZE(free_area); SIZE(list_head); + TYPEDEF_SIZE(nodemask_t); OFFSET(page, flags); OFFSET(page, _count); OFFSET(page, mapping); @@ -1237,6 +1238,7 @@ static int __init crash_save_vmcoreinfo_ OFFSET(list_head, next); OFFSET(list_head, prev); LENGTH(zone.free_area, MAX_ORDER); + NUMBER(NR_FREE_PAGES); arch_crash_save_vmcoreinfo(); _ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
