the arguments of some calls, I will do those separately (later) as
they touch a lot more of the system.

no longer use and/or need it
- removed casts from unionfs, deadfs and fdesc
(there are more to hunt down still)
- changed vfs_quotactl args argumet from caddr_t to void *
- changed vfs_quotactl structures/callers to reflect the api change
Compiled fine and ran for about a day. Approved/reviewed by
christos@netbsd.org and gimpy@netbsd.org.
case, we tear down the node-specific storage as if there were no more open
users. As vclean() will VT_NON the vnode before anyone else will get access
to the vnode, this is our last chance.
Fixes memory leak in revoke(2) path noticed by tedu at openbsd dot org.
called with every buffer written through spec_strategy().
Used by fss(4). Future file-system-internal snapshots will need them too.

VOP_STRATEGY(bp) is replaced by one of two new functions:
- VOP_STRATEGY(vp, bp) Call the strategy routine of vp for bp.
- DEV_STRATEGY(bp) Call the d_strategy routine of bp->b_dev for bp.
DEV_STRATEGY(bp) is used only for block-to-block device situations.
Uses a hook in spec_strategy() to save data written from a mounted
file system to its block device and a hook in dounmount().
Not enabled by default in any kernel config.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded. Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.
PS - I'm sorry, but there's a distinct lack of documentation at the
moment. I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.
accepted. However, this time this behavor is not the default. Instead
it must enabled by using the LOCAL_CONNWAIT socket option on either the
connecting or accepting socket.
to the session and pgrp from the tty. The way that the console is
handled means that the vrele() may not actually do the final close
on the tty itself.
file system.
The function vfs_write_suspend stops all new write operations to a file
system, allows any file system modifying system calls already in progress
to complete, then sync's the file system to disk and returns. The
function vfs_write_resume allows the suspended write operations to
complete.
From FreeBSD with slight modifications.

This means that fstat will report the partition size and hence newfs
needn't grovel into the disklabel to find the filesystem size.
to have KFS or PFS differentiators. Further I have wrapped the enum in
procfs in "#ifdef _KERNEL" as it is done in kernfs.
To see the discussion go to http://mail-index.NetBSD.org/tech-kern/2003/09/
and look for "Mismatched enums in include files" in the list.
genfs_getpages() can read in more blocks than it should due to faked filesize
of lfs_gop_size(). it's a security problem and it makes gcc3 "internal error"
to fix this,
- in genfs_getpages(), always calculate diskeof and memeof separately
so that filesystems (in this case, lfs) can use different strategies
for them.
- introduce GOP_SIZE_MEM flag and use it to request in-core filesize.
(it was an intention of GOP_SIZE_READ,
but after the above change _READ is not a straightforward name)
after this, no one uses GOP_SIZE_{READ,WRITE} anymore but leave them for now.
Handy because ls(1) helpfully converts the time to human-readable
format when printing, and because shell tools like "test -nt" and
"find -newer" can be used against it.
"Inspired" by a discussion about removing lockfiles older than the
last reboot, and Al Crooks' handy observation that a close
approximation can be found with /var/run/dmesg.boot
While here, notice that a lot of the kernfs structures and naming
changed suddenly, and though it seems a clear improvement, there was no
mention in commit logs.
