- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
and factored out some of the vfsop statfs() code to copy_statfs_info(). This
fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.
are vput()/vrele()d as necessary - some filesystems did use the wrong
one for some ops, and it's just safer to not take the chance

* do not set *vpp unless successful, otherwise we'd trigger
DIAGNOSTIC panic in lookup(9) on error return
* on error, make sure to free malloc'ed memory and ungetnewvnode() the
previously acquired vnode
this fixes panic on 'tail -f <file> &; ls -l /proc/$!/fd' reported by

gets reset properly when the old parent exits before the child. A flag
is set in old parent process when the child is reparented in ptrace(2).
If it's set when process is exiting, all running processes have their
'old parent process' pointer checked and reset if appropriate. Also
change to use 'struct proc *' pointer directly, rather than pid_t.

(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
These changes will allow platforms like x86 (XMM) and PowerPC
(AltiVec) to export extended register sets in a sane manner.
* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
/proc/N/xmmregs in procfs.
adjusted via sysctl. file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value. the max number of FFS softdeps is also recalculated.
convert various file systems to use the <sys/queue.h> macros for
their hash tables.
