to give pollution compatible with <nfs/nqfs.h>. At least mount_nfs.c
previously had to #define KERNEL before including <nfs/nfs.h> to get
this pollution, but this gave other pollution.
Moved comment about NFSINT_SIGMASK to immediately before the code that
it applies to.
depend on <sys/types.h> forward declaring common ones.
Added an underscore to `sin' in prototypes to avoid warnings for the
conflict with the ANSI sin().
a BSD4.4Lite1 feature, not a FreeBSD feature. <sys/ioctl.h> is a
compatibility misfeature.
Moved NPCI ifdef. This file didn't compile if NPCI <= 0. It shouldn't
be configured in that case, but it is easy to support (mis)configuration
of drivers without buses by generating null objects, and many drivers
do it.
Removed unused includes.
prematurely when there was a hole (for a cdrom or an unused
interface) in the sequence of wd drives. This caused non-free
wd units to be probed as atapi drives. There was no problem
provided the atapi probe failed correctly.
Fix the SCIOCGETDEVINFO code so that it compiles, and while I'm at it,
add support for human-readable device names so that I don't have
to call devname(3) on the scd->dev to get it.
in kernel Makefiles. Nothing in /usr/include is used (provided
relative paths for sys/* and <machine> can be found), so there is
no need for the -I/usr/include kludge as in kernel Makefiles.
since pkh made tunctl static in revision 1.17 these are already
guaranteed to be zero'd and tunattach will only be called once.

to look up information about that device. Right now, all it does
is give back the dev_t for the device, if known, since that's all
I needed, but hopefully the SCSI mavens will come up with a more generally
useful structure.
MUST be PG_BUSY. It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed. The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use. There were some minor problems
with the collapse code, and this plugs those subtile "holes."
Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages. I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise. For now, we are stuck
with the current morass.
- Remove reference to the obsolete options: BOOT_PROBE_KEYBOARD,
BOOT_PROBE_KEYBOARD_LOCK and BOOT_FORCE_COMCONSOLE.
- Add reference to BOOT_COMCONSOLE_SPEED.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.
If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.
R.I.P
available. If there isn't bounce space available, the bounce code
is disabled. This will allow most large systems to run properly
when the bounce space is mistakenly allocated above 16MB.
All known versions of this drive (firmware 21.* and 23.*) will lock up
if presented with a read/write request of > 64 blocks. In the presence
of such a unit, I/O requests of > 64 blocks are fragmented to avoid
this.
a hashed port list. In the new scheme, in_pcblookup() goes away and is
replaced by a new routine, in_pcblookup_local() for doing the local port
check. Note that this implementation is space inefficient in that the PCB
struct is now too large to fit into 128 bytes. I might deal with this in the
future by using the new zone allocator, but I wanted these changes to be
extensively tested in their current form first.
Also:
1) Fixed off-by-one errors in the port lookup loops in in_pcbbind().
2) Got rid of some unneeded rehashing. Adding a new routine, in_pcbinshash()
to do the initialial hash insertion.
3) Renamed in_pcblookuphash() to in_pcblookup_hash() for easier readability.
4) Added a new routine, in_pcbremlists() to remove the PCB from the various
hash lists.
5) Added/deleted comments where appropriate.
6) Removed unnecessary splnet() locking. In general, the PCB functions should
be called at splnet()...there are unfortunately a few exceptions, however.
7) Reorganized a few structs for better cache line behavior.
8) Killed my TCP_ACK_HACK kludge. It may come back in a different form in
the future, however.
These changes have been tested on wcarchive for more than a month. In tests
done here, connection establishment overhead is reduced by more than 50
times, thus getting rid of one of the major networking scalability problems.
Still to do: make tcp_fastimo/tcp_slowtimo scale well for systems with a
large number of connections. tcp_fastimo is easy; tcp_slowtimo is difficult.

them in the include path. This fixes recent breakage of the syscons
LKMs and general brokenness of the include paths (headers under
/usr/include were used in many cases).
6x86MX CPU is enabled (BIOS should not disable it), some BIOS disables
it via CCR4. In this case, cpu variable becomes CPU_486 and
identblue() is called. Because Cyrix 6x86MX has MSR and doesn't have
MSR1002, wrmsr instruction generates general protection fault.

Make vfs_bio buffer mgmt work better.
Buffers were being used after brelse.
Make nfs_getpages work independently of other NFS
interfaces. This eliminates some difficult
recursion problems and decreases pagefault
overhead.
Remove an erroneous vfs_unbusy_pages.
Fix a reentrancy problem, with nfs_vinvalbuf when
vnode is already being rundown.
Reassignbuf wasn't being called when needed under
certain circumstances.
(Thanks to Bill Paul for help.)

This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)
LFS is temporarily disabled, and will be re-enabled tomorrow.
