I've found that current src/sys/modules/linux for RELENG_4 is not
'make -j' safe. It maybe causes a problem if you want to make a
module. This problem comes from recent MI/MD changes to linux module.
Here is a sample session:
% make obj
/usr/obj/usr/src/sys/modules/linux created for /usr/src/sys/modules/linux
% make -j 2
@ -> /usr/src/sys
machine -> /usr/src/sys/i386/include
echo "#define COMPAT_43 1" > opt_compat.h
touch opt_linux.h
touch opt_vmpage.h
gzip -cn /usr/src/sys/modules/linux/linux.8 > linux.8.gz
perl @/kern/vnode_if.pl -h @/kern/vnode_if.src
sh @/kern/makesyscalls.sh @/i386/linux/syscalls.master @/i386/linux/syscalls.conf
sh @/kern/makesyscalls.sh @/i386/linux/syscalls.master @/i386/linux/syscalls.conf
sed -e 's|i386/linux/linux_proto\.h|linux_proto.h|g' linux_sysent.c > linux_sysent.c.fixup
mv -f linux_sysent.c.fixup linux_sysent.c
sed -e 's|i386/linux/linux_proto\.h|linux_proto.h|g' linux_sysent.c > linux_sysent.c.fixup
mv -f linux_sysent.c.fixup linux_sysent.c

*** Error code 1

This is because linux_sysent.c is broken:
% ls -l /usr/obj/usr/src/sys/modules/linux/linux_sysent.c
-rw-r--r-- 1 root wheel 29487 Nov 3 20:48 /usr/obj/usr/src/sys/modules/linux/linux_sysent.c
% grep linux_sysent /usr/obj/usr/src/sys/modules/linux/linux_sysent.c
struct sysent linux_sysent[] = {
struct sysent linux_sysent[] = {
It seems that this file contains two linux_sysent[] definition.
