It should be safe. This tells me nothing about whether the initrd is actually /used/. What it tells me is that it's being freed. The function of an initrd is not to be a chunk of memory which gets freed later on in the boot process. It is there to provide an "initial ramdisk" (whether it be a filesystem image, or a CPIO compressed archive) for userspace to run. So, have you checked that initrd is still functional after this patch? -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
