Description

The current kernel version is 6.1.x, but makedumpfile(1.7.2) only supports kernel version from KERNEL_VERSION(2, 6, 15) to KERNEL_VERSION(6, 0, 1).

makedumpfile.h

#define KERNEL_VERSION(x,y,z) (((x) << KVER_MAJ_SHIFT) | ((y) << KVER_MIN_SHIFT) | (z))
#define OLDEST_VERSION		KERNEL_VERSION(2, 6, 15) /* linux-2.6.15 */
#define LATEST_VERSION		KERNEL_VERSION(6, 0, 1) /* linux-6.0.1 */

makedumpfile.c

	version = KERNEL_VERSION(maj, min, rel);

	if ((version < OLDEST_VERSION) || (LATEST_VERSION < version)) {
		MSG("The kernel version is not supported.\n");
		MSG("The makedumpfile operation may be incomplete.\n");
	}


When running makedumpfile we will encounter the following warning:
$ makedumpfile -f --mem-usage /proc/kcore 
The kernel version is not supported.
The makedumpfile operation may be incomplete.
