sense. Since portmap/rpcbind is in /usr/sbin it doesn't make any sense for
nfsd and mountd to be in /sbin.
For the record, NetBSD has them in /usr/sbin while OpenBSD has them in /sbin

the new content size fits into the sbuf, instead of assuming
that allocating twice the old size is enough.
- Use memmove(3) rather than strcpy(3) to copy overlapping

Tell vop_strategy_pre() to use this instead.

exist so they don't have to be. This isn't ideal but it is safe.
vm_mmap() as well as the GETATTR etc.
- If the handle is a vnode in vm_mmap() assert that it is locked.
- Wiggle Giant around a little to account for the extra vnode operation.
They provided little benefit (if any) and they caused some problems
in OpenOffice, at least in post-KSE -current and perhaps in other
environments too. The nanosleep calls prevented the profiling timer
from advancing during the spinloops, thereby preventing the thread
scheduler from ever pre-empting the spinning thread. Alexander
Kabaev diagnosed this problem, Martin Blapp helped with testing,
and Matt Dillon provided some helpful suggestions.
This is a short-term fix for a larger problem. The use of spinlocking
isn't guaranteed to work in all cases. For example, if the spinning
thread has higher priority than all other threads, it may never be
pre-empted, and the thread holding the lock may never progress far
enough to release the lock. On the other hand, spinlocking is the
only locking that can work with an arbitrary unknown threads package.
I have some ideas for a much better fix in the longer term. It
would eliminate all locking inside the dynamic linker by making it
safe for symbol lookups and lazy binding to proceed in parallel
with a call to dlopen or dlclose. This means that the only mutual
exclusion needed would be to prevent multiple simultaneous calls
to dlopen and/or dlclose. That mutual exclusion could be put into
the native pthreads library. Applications using foreign threads
packages would have to make their own arrangements to ensure that
they did not have multiple threads in dlopen and/or dlclose -- a
reasonable requirement in my opinion.

Changed release notes: KSE (rewrite and status update), Binutils
2.12.1 (20020622 snapshot).
MFCs noted: libpcap-0.7.1, tcpdump-3.7.1, OpenSSH through 3.4p1.
Also retroactively note some OpenSSH items as MFC-ed and historic.
I'm not sure when these were merged, but I'm pretty sure it was a long
time ago.
- Cache a pointer to the vnode's object in the buf.
- Hold a reference to that object in addition to the vnode's reference just
to be consistent.
- Cleanup code that got the object indirectly through the vp and VOP calls.
This fixes at least one case where we were calling GETVOBJECT without a lock.
It also avoids an expensive layered call at the cost of another pointer in
struct buf.
