supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and
remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).
Based on a diff from tedu.

errnos. Note that the error strings are being ignored, since we long ago
decided to not spam the console, and there is no other nice way to use the
errors (without changing the ioctls to pass it back)
The errno is now useful, since we can pass b_error from failing IO up, and
the drive can decide how to use that

information about the various structs used within the kernel, and have
new ddb commands allowing struct display and some useful information
gathering. Kernel rodata increase varies accross platforms from ~150KB to
~300KB.

No longer allocate a static amount of memory for messages in MD
boot path; message queues, message metadata, and message data now
all use dynamic memory, which means that runtime sysctls should now
be trivial to implement.
Since I'm going to be around all week to fix any breakage, this should
probably just go in now.

1) The sysctl allowing bufcachepercent to be changed at boot time.
2) The change moving the buffer cache hash chains to a red-black tree
3) The dynamic buffer cache (Which depended on the earlier too).

bounds information, ie. the zone of the disk that OpenBSD can use. Have each
pre-disklabel parser (MBR, DPME, or per-arch MD disklabel parsers) figure out
this area and pass it up to userland. Then, delete all the same disk parsing
code from disklabel(8) since the kernel passes it up. Lots and lots of - signs
in the disklabel(8) code.
Tested on as many platforms as possible, the fallout will be repaired as time
goes on. To test, use disklabel -d <drive> and validate that the bounds do not
overlap any boot blocks. This same information is used by disklabel -A...

What happened was that the output of mkdep was fed to a sed expression
that trimmed a bit more than required and also failed to work when
attempting to do make depend with pcc.
Example:
genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \
was changed to:
assym.h: \
but what was intended was:
assym.h: ../../../../../sys/param.h \
For the pcc -M output things were a bit different and after the make
depend the genassym entry would still remain and make would fail. This
affected all platforms except amd64 and sgi.
Okay miod@.

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.
