Fair enough. We should be pretty careful about what we put in meminfo - it's the top-level, most-important procfs file and I expect that quite a lot of userspace reads it with some frequency. We don't want to clutter it up. /proc/vmstat is a suitable place for the less important info which is more kernel developer oriented. But CMATotal and CMAFree do pass the "should be in meminfo" test, IMO. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
