[oclug] driver&RedHat7

[Bart Trojanowski]

That's pretty much it.  Make sure that your module - when compiled - uses
the proper kernel include tree (ie: /usr/src/linux-2.4.00-test8/include).
More specifically /usr/src/linux*/include/linux/version.h contains the
version info of that kernel.  

It is recomened that CONFIG_MODVERSIONS is set in the kernel .config file
if you have modules compiled that come from outside of the kernel
tree.  This option makes kernel modules less dependant on the version of
the kernel.  You can read more about this in Documentation/Configure.help
under CONFIG_MODVERSIONS and Documentation/modules.txt.

Even if you use CONFIG_MODVERSIONS, I would be surprised that you would
not need to recompile your module between 2.2.x and 2.4.x.  A lot of
functions became macros and visa versa.  That makes function lookups for
some things imposible.
