can sleep on the vnode lock, while vget is sleeping on the
VI_INACTNOW flag (or the vget caller is looping on vget returning failure
because of the VI_INACTNOW flag). With layered FSes, the upper and lower
vnodes share the same lock, so the vget() caller above can be already
holding the vnode lock.
Fix by dropping VI_INACTNOW before sleeping on the vnode lock in
vrelel(), and check the ref count again once we have the lock. If the
vnode has more than one reference, donc VOP_INACTIVE it.

This is a temporary fix to allow pullups to existing, supported versions
of NetBSD. I will follow up with a version for current using the new
getline function.
According to http://cvs.savannah.gnu.org/viewvc/ccvs/src/?root=cvs
this was broken between revs 1.29 and 1.32 for a perion of 4 months
about 4 years ago.
Not sure at all why/how we have the broken version.
Our old code, the latest gnu code and this fix all differ slightly,
but have the same effect.
It just fakes MBR partition map which contains 1MB FAT16B partition
and ~1GB OpenBSD partition, and we can always create necessary
MBR partitions for OpenFirmware by the fdisk(8) command itself.
update builds too, flip the allocator define to prefer the kernel
pool/kmem instead of malloc(3). Use malloc(3) only if
RUMP_USE_UNREAL_ALLOCATORS is defined.
don't add ${CPPFLAGS_ISYSTEM} or ${CPPFLAGS_ISYSTEMXX} to refer
${DESTDIR}/usr/include or ${DESTDIR}/usr/include/g++.
This change might cause errors on some MD stand dir, but in that case
each Makefile should be fixed to search proper system include paths
by -Ipath option in own CPPFLAGS.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
currently there. Still needs a little massage to get the kernel
interfaces right and avoid copypaste especially from main().
Also, move it a bit more into the direction of a real file system
(finally!) by giving it a vfsops. Most ops are still unimplemented,
though.
