Any existing config files (using the -f option) will need
to be changed although using the old files will usually result
in an error (partition 0 is invalid).
writes sent to the server were synchronous and therefore no commits are
needed. This is the same as the vfs.nfs.async variable on the server but
allows each client to choose whether to work this way.
Also make the vfs.nfs.async variable do the 'right' thing for NFSv3, i.e.
pretend that the write was synchronous.
attached to the vnode, some of them could be re-written synchronously
(if they overflowed the fixed size array nfs_flush had for them). The
fix involves mallocing an array if there are more than its limited
size stack buffer.

These commands are required for the "Disk-At-Once" write process:
WORMIOCREADSESSIONINFO returns the length of the lead-in and lead-out areas
and WORMIOCWRITESESSION is used to send the table of contents of the disk.
device probe of a host to PCI bridge may modify that value, based on
its knowledge of device specific registers. This makes the Intel XXpress
work, as verified by: Terje Marthinussen <terjem@cc.uit.no>.
bit 10 is the old bit for MTRR (presumably this changed, an older P5 I
have has got it, the newer cpus have the new MTRR bit set)
bit 11 is SEP (fast syscalls), bit 23 is MMX
Fill in the other reserved ones with a stub so that we can see them if
they turn up.

semantics of the old sleep for compatability with a few decades of expected
side effects. Apache breaks if we just use nanosleep() for some reason,
here we use a new signanosleep() syscall which is kinda like a hybrid of
sigsuspend and nanosleep..

sleep used plain nanosleep)
license managers to obtain the host's ethernet address as
a key.
Note that this implementation takes the first hardware address for
the first ethernet interface found, and disregards the interface name
that may be passed in, as linux ethernet devices are all "ethX".
These changes add the ability to specify that a UFS file/directory
cannot be unlinked. This is basically a scaled back version
of the IMMUTABLE flag. The reason is to allow an administrator
to create a directory hierarchy that a group of users
can arbitrarily add/delete files from, but that the hierarchy
itself is safe from removal by them.
If the NOUNLINK definition is set to 0
then this results in no change to what happens normally.
(and results in identical binary (in the kernel)).
It can be proven that if this bit is never set by the admin,
no new behaviour is introduced..
Several "good idea" comments from reviewers plus one grumble
about creeping featurism.
This code is in production in 2.2 based systems
these are quite extensive additions to the ipfw code.
they include a change to the API because the old method was
broken, but the user view is kept the same.
The new code allows a particular match to skip forward to a particular
line number, so that blocks of rules can be
used without checking all the intervening rules.
There are also many more ways of rejecting
connections especially TCP related, and
many many more ...
