and we have lift-off

Shortly after my first OOPs, I now have my first useful (to me only) kernel modification:

Now when I do a megaraid ioctl (be it from an open source or closed-source utility),

sammy:/usr/src/linux-2.6# ./megadm.pl
Number of adapters: 0 but true

Then dmesg shows what the ioctl was:

megaraid cmm: 2.20.2.0 (Release Date: Thu Aug 19 09:58:33 EDT 2004) (BF modified)
megaraid: 2.20.4.0 (Release Date: Mon Sep 27 22:15:07 EDT 2004)
BF: mega ioctl in: in=0 out=0 op=130 subop=109 adapno=0 buf=0 len=0
dump: [00 00 00 00 00 00 00 00 ffffff82 6d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 30 16 08 00 00 00 00 ]
