RE: missing symbols...

Just to chime in as an update here.

To make things work on RHEL4 x86_64 I had to remove the sleep_on()
function, lis_sleep_on(), because it is in fact not exported as
Edward
pointed out.  It's not really clear to me what this is even used for.
Anyone in the LiS community going to be upset if this function goes
away? (Not that you really have much choice)  I know that we don't
use it at all.

Also, I put in Edward's trick of just inserting the body of
cdev_put()
in place of cdev_put and that does seem to work fine for RHEL 4.0.

Another silly "feature" of RHEL 4.0 is that if you use the kbuild
method to build your drivers (that is $(MAKE) -C /usr/src/linux -M
`pwd` modules), RHEL 4.0 gives you -Os and -g for gcc flags by
default.  Ugh.  This meant that I had to go around adding 'strip -d
<filename>' to all my makefiles to get rid of all of the debugging
crap.  Just to let you know...

thanks-
