Hi Paul,

Since BenH fixed the _set_L2CR() function, I have been able to shorten
the l2cr command line code. Attached is the patch vs. your current 2.4
rsync tree. I've not been able for a long time to boot a 2.4 kernel, but
it never crashed in this part ;-)

Anyway, all the patch does is to actually enable the processing of l2cr=
command lines.

Thanks for including this if you have no objection.

Cheers

Michel

PS Patch also posted to sourceforge.
