o The partition label can be the empty string. It's how labels are
cleared.
o When an action fails, lower permissions when they were raised
in order to allow the action. A failed action will not result
in any uncommitted changes.
o Allow the flags paremeter to be present but empty. It's the
equivalent of not being present.
processes under 64-bit kernels). Previously, each 32-bit process overwrote
its resource limits at exec() time. The problem with this approach is that
the new limits affect all child processes of the 32-bit process, including
if the child process forks and execs a 64-bit process. To fix this, don't
ovewrite the resource limits during exec(). Instead, sv_fixlimits() is
now replaced with a different function sv_fixlimit() which asks the ABI to
sanitize a single resource limit. We then use this when querying and
setting resource limits. Thus, if a 32-bit process sets a limit, then
that new limit will be inherited by future children. However, if the
32-bit process doesn't change a limit, then a future 64-bit child will
see the "full" 64-bit limit rather than the 32-bit limit.
MFC is tentative since it will break the ABI of old linux.ko modules (no
other modules are affected).

SIGCHLD/kevent(2) notification of process termination and wait(). Now
we no longer drop locks between sending the notification and marking
the process as a zombie. Previously, if another process attempted to do
a wait() with W_NOHANG after receiving a SIGCHLD or kevent and locked
the process while the exiting thread was in cpu_exit(), then wait() would
fail to find the process, which is quite astonishing to the process
calling wait().

config(8) in order to prevent yourself from seeing a warning about old
version of that tool.
You should configure the kernel with a new config(8) then.

This change will let us to have full configuration of a running kernel
available in sysctl:
sysctl -b kern.conftxt
The same configuration is also contained within the kernel image. It can be
obtained with:
config -x <kernelfile>
Current functionality lets you to quickly recover kernel configuration, by
simply redirecting output from commands presented above and starting kernel
build procedure. "include" statements are also honored, which means options
and devices from included files are also included.
Please note that comments from configuration files are not preserved by
default. In order to preserve them, you can use -C flag for config(8). This
will bring configuration file and included files literally; however,
redirection to a file no longer works directly.

protocol entry points using functions named proto_getsockaddr and
proto_getpeeraddr rather than proto_setsockaddr and proto_setpeeraddr.
While it's true that sockaddrs are allocated and set, the net effect is
to retrieve (get) the socket address or peer address from a socket, not
set it, so align names to that intent.
