- Don't use realpath as stat does the right thing.
- Only check ufs filesystems in getmntpt.
- Dont' bother checking that the ufs-mounted-on
device is a special file. It *must* be a special
file, or ufs wouldn't have mounted it.

Driver is not functional yet, but does compile. Tests with xe cards
indicates that it doesn't panic the machine when they are present, but
fail to probe. Interface help in the pcic/pccard layers are needed to
complete this driver.
o ifdef out pccardchip.h (almost all of it, there are dangling bits
o Add rid/res members to pccard_function
o remove pct/pch from pccard_softc
o map memory properly in scan_cis (almost, see XXX for more work)
o manage ccr.
o remove bogus comment I added about touching the ccr being a layering
violation for pccard. It is properly done at that level.
o More function prototyping
whilst we are playing or recording. since we should irq ~20 times/sec when
active, this should never trigger. in theory. if it never does trigger,
the check will be removed.
with kld etc just fine, but tracebacks would have less information and
nm /kernel wouldn't be so good).
- Just strip the kernel on the boot disk. This does not affect kld or
module loading, there are two symbol tables in a kernel. There is the
dynamic linking one (.dynsym+.strtab) with just global symbols and a user
symbol table (.symtab+.strtab) with all symbols. BTW; objdump lies and
hides the second one. There's a good half a meg or so that can be saved
from an average kernel by stripping it.

needs to be more aware that a process may actually disappear while it's
waiting.

o Realloc memory leak fixed which won't matter but would trigger purify
o Default to sendmail when no mailer.conf exists.
Fixed bugs in OpenBSD version:
o Add NULL termination in the right place.
Also put back the err. free shouldn't touch errno.

o Properly terminate argv list with a NULL entry.
o Use warn() to report the exec failure because free could change errno and

o Don't terminate string to err with ':' since this results in two colons.
1) Fastpath deletions. When a file is being deleted, check to see if it
was so recently created that its inode has not yet been written to
disk. If so, the delete can proceed to immediately free the inode.
2) Background writes: No file or block allocations can be done while the
bitmap is being written to disk. To avoid these stalls, the bitmap is
copied to another buffer which is written thus leaving the original
available for futher allocations.
3) Link count tracking. Constantly track the difference in i_effnlink and
i_nlink so that inodes that have had no change other than i_effnlink
need not be written.
4) Identify buffers with rollback dependencies so that the buffer flushing
daemon can choose to skip over them.
it only on the buf_daemon process). The problem is that when the
syncer process starts running the worklist, it wants to delete
lots of files. It does this by VFS_VGET'ing the vnodes, clearing
the blocks in them and bdwrite'ing the buffer. It can process close
to a thousand files per second which generates a large number of
dirty buffers. So, giving it special priviledge at the buffer trough
leads to trouble as the buf_daemon does occationally need a free
buffer to proceed and if the syncer has used every last one up,
we are toast.

and freefile structures. Limit the rate of buffer dirtying by the
syncer process during periods of intense file removal.
check before the inode is unlocked while grabbing its parent directory.
Once it is unlocked, other operations may slip in that could make
the inode-is-flushed check fail. Allowing other writes to the inode
before returning from fsync does not break the semantics of fsync
since we have flushed everything that was dirty at the time of the
fsync call.
init and fini functions. Now the code is very careful to hold no
locks when calling these functions. Thus the dynamic linker cannot
be re-entered with a lock already held.
Remove the tolerance for recursive locking that I added in revision
1.2 of dllockinit.c. Recursive locking shouldn't happen any more.
Mozilla and JDK users: I'd appreciate confirmation that things still
work right (or at least the same) with these changes.
While here fix some minor style bugs (whitespacing) and move the
make target from Makefile.upgrade to this file.
Simplify the make target to make it readable.
