very slow process, especially for large file systems that is just
recovered from a crash.
Since the summary is already re-sync'ed every 30 second, we will
not lag behind too much after a crash. With this consideration
in mind, it is more reasonable to transfer the responsibility to
background fsck, to reduce the delay after a crash.
Add a new sysctl variable, vfs.ffs.compute_summary_at_mount, to
control this behavior. When set to nonzero, we will get the
"old" behavior, that the summary is computed immediately at mount
time.
Add five new sysctl variables to adjust ndir, nbfree, nifree,
nffree and numclusters respectively. Teach fsck_ffs about these
API, however, intentionally not to check the existence, since
kernels without these sysctls must have recomputed the summary
and hence no adjustments are necessary.
This change has eliminated the usual tens of minutes of delay of
mounting large dirty volumes.

preliminary support for using the GCC-compatibility of ICC was committed
but couldn't be tested at that time due to problems with ICC itself. Since
ICC 8.1 it's possible to use its GCC-compatibility under FreeBSD and it
turned out that a typedef for __gnuc_va_list is required in that case.
Revert the part of rev. 1.8 which #ifdef'ed out __gnuc_va_list for ICC.

patch from kan@).
Pull bufobj_invalbuf() out of vinvalbuf() and make g_vfs call it on
close. This is not yet a generally safe function, but for this very
specific use it is safe. This solves the problem with buffers not
being flushed by unmount or after failed mount attempts.
a packet has VLAN mbuf tag attached. This is faster to check than
m_tag_locate(), and allows us to use the tags in non-vlan(4) VLAN
producers.
The first argument to VLAN_OUTPUT_TAG() is now unused but retained
for backward compatibility.
While here, embellish a fix in rev. 1.174 of if_ethersubr.c -- it
now checks for packets with VLAN (mbuf) tags, and it should now
be possible to bridge(4) on vlan(4)'s whose parent interfaces
support VLAN decapsulation in hardware.

like a valid range. We already do this in the memory case (although
the code there is somewhat different than the I/o case because we have
to deal with different kinds of memory). Since most laptops don't
have non-subtractive bridges, this wasn't seen in practice.
Evidentally the Compaq R3000 hits this problem with PC Cards.

Most file systems don't generate log messages based on details of the
file system superblock, and these log messages disrupt sysinstall output
during a new install from CD. We may want to explore exposing this
status information using nmount() at some point.

copy op to shift arguments on the stack instead of transfering each
argument one by one through a register. Probably doesn't affect overall

so->so_options when solisten() will succeed, rather than setting it
conditionally based on there not being queued sockets in the completed
socket queue. Otherwise, if the protocol exposes new sockets via the
completed queue before solisten() completes, the listen() system call
will succeed, but the socket and protocol state will be out of sync.
For TCP, this didn't happen in practice, as the TCP code will panic if
a new connection comes in after the tcpcb has been transitioned to a
listening state but the socket doesn't have SO_ACCEPTCONN set.
This is historical behavior resulting from bitrot since 4.3BSD, in which
that line of code was associated with the conditional NULL'ing of the
connection queue pointers (one-time initialization to be performed
during the transition to a listening socket), which are now initialized
separately.

(For example, you don't have to pass an array of cf_setting just to find

Use this new method in our in-tree drivers to detect reliably if acpi_perf

as fixing a bug introduced in my last commit where too many drivers attached.

testing for this case inside of the if statement results in dead code.
We'd fail to set a value to zero that's already zero (since it is
initialized to 0 indirectly) with this code being there. Well, except
in the very rare case that we have a card that has a defualt entry
that includes a memory space followed by one that has no memory space
(these are extremely rare, I don't recall ever having seen one :-).
Fix this by setting num_memspace to 0 in a more appropriate place.
