Hmm, to be honest I don't know what FIOSETOWN/FIOGETOWN do exactly, but
the following two patches to the linux lkm seem to work for me (at least
with respect to running the Linux JDK):

The FIOGETOWN stuff is commented out because I don't know what
the value of LINUX_FIOGETOWN is - I don't have a Linux system so
that I could look at that header file mentioned in the previous
message.
But I don't know - maybe it shouldn't be this simple - maybe FIOSETOWN
in Linux is different from that in FreeBSD. FreeBSD's is defined in
/usr/include/sys/filio.h ("Generic file-descriptor ioctl's")
whereas Linux's seems to be defined in a file with other socket
level ioctl's. I briefly read through sys/kern/sys_generic.c to
understand what FIOSETOWN/FIOGETOWN do, but I'm still confused.
Oh, I'm running 3.0-current as of 97.02.10.00.00.00 (cvsup notation)
which is pre-Lite2.

Pius
