ACPI: Remove ACPI_CUSTOM_DSDT_INITRD option

2008-03-15T18:58:04Z

This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.

ACPI: basic initramfs DSDT override support

2008-02-07T03:07:41Z

The basics of DSDT from initramfs. In case this option is selected, populate_rootfs() is called a bit earlier to have the initramfs content available during ACPI initialization. This is a very similar path to the one available at http://gaugusch.at/kernel.shtml but with some update in the documentation, default set to No and the change of populate_rootfs() the "Jeff Mahony way" (which avoids reading the initramfs twice).

Remove superfluous checks for CONFIG_BLK_DEV_INITRD from initramfs.c

2008-02-06T18:41:06Z

Given that init/Makefile includes initramfs.c in the build only if CONFIG_BLK_DEV_INITRD is defined, there seems to be no point checking for it yet again. Signed-off-by: Robert P. J. Day Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Add retain_initrd boot option

2007-02-11T18:51:24Z

Add retain_initrd option to control freeing of initrd memory after extraction. By default, free memory as previously. The first boot will need to hold a copy of the in memory fs for the second boot. This image can be large (much larger than the kernel), hence we can save time when the memory loader is slow. Also, it reduces the memory footprint while extracting the first boot since you don't need another copy of the fs.

Make sure we populate the initroot filesystem late enough

2006-12-11T20:12:04Z

We should not initialize rootfs before all the core initializers have run. So do it as a separate stage just before starting the regular driver initializers. Signed-off-by: Linus Torvalds

[PATCH] Make initramfs printk a warning on incorrect cpio type

2006-12-07T16:39:36Z

It turns out that the "-c" option of cpio is highly unportable even between distros let alone unix variants, and may actually make the wrong type of cpio archive. I just wasted quite some time on this, and the kernel can detect this and warn about it (it's __init memory so it gets thrown away and thus there is no runtime overhead) Signed-off-by: Arjan van de Ven Cc: Al Viro Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] initramfs overwrite fix

2006-06-26T16:58:40Z

This patch ensures that initramfs overwrites work correctly, even when dealing with device nodes of different types. Furthermore, when replacing a file which already exists, we must make very certain that we truncate the existing file. Signed-off-by: H.

[PATCH] initramfs: fix CPIO hardlink check

2006-05-15T18:20:55Z

Copy the filenames of hardlinks when inserting them into the hash, since the "name" pointer may point to scratch space (name_buf). Not doing so results in corruption if the scratch space is later overwritten: the wrong file may be hardlinked, or, if the scratch space contains garbage, the link will fail and a 0-byte file will be created instead.

[PATCH] Fix typo causing bad mode of /initrd.image

2006-03-26T16:56:58Z

I noticed that after boot with an initrd in 2.6.16 the rootfs had: --w-r-xr-T 1 root root 6241141 Jan 1 1970 initrd.image Which is caused by a small typo: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
