Subject: 2.4.18 --> 2.4.19. Ramdisk requires floppy?
Date: Tue, 3 Sep 2002 18:51:33 +0200 [thread overview]
Message-ID: <20020903165133.GA8726@southpole.se> (raw)
Hi,
I've noticed that the 2.4.19 version of "prepare_namespace"
(init/do_mounts.c) not allows you to mount a non floppy as a
ramdisk(?). This has changed since 2.4.18 (split of main.c ->
{do_mounts,main}.c).
2.4.18 does a very simple check (below):
--- 2.4.18 ---
#ifdef CONFIG_BLK_DEV_RAM
#ifdef CONFIG_BLK_DEV_INITRD
if (mount_initrd)
initrd_load();
else
#endif
rd_load();
#endif
--- 2.4.18 ---
however, in 2.4.19 it just tries to load a ramdisk if it's on a
floppy. Why? There may still be a ramdisk on an other device, NOT
using initrd.
--- 2.4.19 ---
if (mount_initrd) {
if (initrd_load() && ROOT_DEV != MKDEV(RAMDISK_MAJOR, 0)) {
handle_initrd();
goto out;
}
} else if (is_floppy && rd_doload && rd_load_disk(0))
ROOT_DEV = MKDEV(RAMDISK_MAJOR, 0);
mount_root();
out:
--- 2.4.19 ---
