Eric, thanks for your answer.

I'm aware that vendor-patched trees are quite unsupported on general
kernel lists, but, please, bear with me a little... to which kernel tree
does the above apply? I'm asking because:

# find /usr/src/linux/. -type f | xargs fgrep COMPATIBLE_IOCTL
<no results>

# rpm -q kernel-source
kernel-source-2.2.19-6.2.12

that's the Red Hat kernel tree.

I'm pretty willing to grab another tree and compile it, but I'd like to
know which one in advance instead of going on by trial & error. The system
is Red Hat 6.2 so I need a 2.2.x kernel.

.TM.
