. Much reworking of the disk IO scheduler patches due to the updated
dynamic-disk-request-allocation patch. No real functional changes here.
. Included the `kexec' patch - load Linux from Linux. Various people want
this for various reasons. I like the idea of going from a login prompt to
"Calibrating delay loop" in 0.5 seconds.
I tried it on four machines and it worked with small glitches on three of
them, and wedged up the fourth. So if it is to proceed this code needs
help with testing and careful bug reporting please.
There's a femto-HOWTO in the patch itself, reproduced here:
- enable kexec in config, build, install.
- grab kexec-tools from
http://www.osdl.org/archive/andyp/kexec/2.5.68/
- edit ./kexec/kexec-syscall.c and make sure __NR_kexec_load is set
to 269 (-mm kernels have an additional syscall)
- run `make distclean' and `make'
- I use this script:
#!/bin/sh
usage()
{
echo "Usage: do-kexec.sh /boot/bzImage [commandline options]"
exit 1
}
if [ $# -lt 1 ]
then
usage
fi
sync
IMAGE=$1
shift
./objdir/build/sbin/kexec -l $IMAGE --command-line="$(cat /proc/cmdline) $*"
./objdir/build/sbin/kexec -e
invoked as
cd /usr/src/kexec-tools
./do-kexec.sh /boot/bzImage-2.5.68
This is fairly crude - it's an instant reboot, no shutdown or anything.
Only do this if you're using journalled filesystems!
