command line options. The "jail_<jname>_*" rc.conf(5) variables for
per-jail configuration are automatically converted to
/var/run/jail.<jname>.conf before the jail(8) utility is invoked.
This is transparently backward compatible.
- Fix a minor bug in jail(8) which prevented it from returning false

is ignored except for "rc.d/netif vnet{up,down} ifn" because a jail is
usually created after interface initialization on boot time.
"rc.d/netif vnetup ifn" moves ifn into the specified jail. It is
designed to be used in other scripts like rc.d/jail, not automatically
invoked during the interface initialization.

don't make sense on FreeBSD. In particular,
- remove the ATTRIBUTES section,
- remove references to the Solaris Dynamic Tracing Guide, except in the
SEE ALSO section,
- update the description of the -A option for FreeBSD's implementation,
- remove references to Solaris-specific programs and configuration files,
and replace them with FreeBSD equivalents where possible.
The content has not changed aside from this.

the 2 read-only bytes at the start of a PCI capability.
This is the sequence that OpenBSD uses when enabling
MSI interrupts, and works fine on real h/w.
In bhyve, convert the 4 byte write to a 2-byte write to
the r/w area past the first 2 r/o bytes of a capability.

really belong to it. Such vnodes, with the pointers to other vnodes
v_objects, are typically instantiated by the bypass filesystems.
Invalidating mappings of other vnode pages and the pages is wrong,
since reclamation of the upper vnode does not imply that lower vnode
is reclaimed too.
One of the consequences of the improper reclamation was destruction of
the wired mappings of the lower vnode pages, triggering miscellaneous
assertions in the VM system.

threads still performing unlocked accesses to it.
Grow the table exponentially instead of increasing its size by
sizeof(long) * 8 chunks when overflowing. This mode significantly
reduces the total memory use for the processes consuming large numbers
of the file descriptors which open them one by one.

- This version has support for the new Intel Avoton systems,
including 2.5Gb support, further it now has IPv6/TSO6 support as
well. Shared code has been updated where necessary as well. Thanks
to my new assistant Eric Joyner for doing the transmit path changes
to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the
one bug and change needed in NETMAP.

Also, consolidate a single instance of double-newline and remove some
