applying kernel Raid patch to Vanilla 2.2.20

[Ken Walker <ken.walker@manchester.ac.uk>]

I'm getting really confused.

I can't install anything but Vanilla kernel 2.2.20 because 3.0ra5 and 3.1
hand during install on my advancesys scsi card.

And i want to run a raid drive, mdadm keeps telling me it needs ver 0.9 of
summat.


So i got the file kernel-patch-2.2.20-raid_4_all.deb.

i was reading an article at http://homex.subnet.at/~max/comp-15_raid.php and
it says,

Get the raid-0.90-patch "raid-2.2.19-A1" from
http://people.redhat.com/mingo/raid-patches/ and copy it to /usr/src.

  cd /usr/src
  patch -p0 < raid-2.2.19-A1

I got the suggested copy, but one called raid-2.2.2--A0 and did what he
suggested but i got several hump fails. Humps are quite daunting whey you
don't know what your doing :o(


So i then found the .deb package, which i thought would be more suitable,
cos it's deb

So i downloaded it and did a 

dpkg-deb -x kernel-patch-2.2.20-radi_4_all.deb /usr/src/

but it gave me lots and lots of subdirectories under /usr/src and files
called apply, unpatch and raid.bz2, which isn't mentioned in the how to
above.


It created

/usr/src/usr
/usr/src/usr/share
/usr/src/usr/src
/usr/src/usr/share/doc
/usr/src/usr/share/doc/kernel-patch-2.2.20-raid
/usr/src/usr/src/kernel-patches
/usr/src/usr/src/kernel-patches/i386
/usr/src/usr/src/kernel-patches/i386/2.2.20
/usr/src/usr/src/kernel-patches/i386/2.2.20/apply  raid.bz2  unpatch



So i'm confused as to what to do.

Can anybody point me in the right direction for applying the raid patch and
going from there.


Many thanks
