and KASSERT coverage.
After this check there is only one "nasty" cast in this code but there
is a KASSERT to protect against the wrong argument structure behind
that cast.
Un-inlining the meat of VOP_FOO() saves 35kB of text segment on a typical
kernel with no change in performance.
We also now run the checking and tracing on VOP's which have been layered
by nullfs, umapfs, deadfs or unionfs.
Add new (non-inline) VOP_FOO_AP() functions which take a "struct
foo_args" argument and does everything the VOP_FOO() macros
used to do with checks and debugging code.
Add KASSERT to VOP_FOO_AP() check for argument type being
correct.
Slim down VOP_FOO() inline functions to just stuff arguments
into the struct foo_args and call VOP_FOO_AP().
Put function pointer to VOP_FOO_AP() into vop_foo_desc structure
and make VCALL() use it instead of the current offsetoff() hack.
Retire vcall() which implemented the offsetoff()
Make deadfs and unionfs use VOP_FOO_AP() calls instead of
VCALL(), we know which specific call we want already.
Remove unneeded arguments to VCALL() in nullfs and umapfs bypass
functions.
Remove unused vdesc_offset and VOFFSET().
Generally improve style/readability of the generated code.
so we need to acquire Giant in netgraph methods, so that we don't
race with line discipline methods. Remove NET_NEEDS_GIANT.
- Packets coming into node from netgraph are queued in ifqueue
attached to node private data.
- Mutex in struct ifqueue is used to lock not only the queue, but
the whole private data, and tp->t_lsc field.
- tp->t_lsc pointer is used to indicate whether line discipline is
attached to netgraph or not.
- Use FLG_DIE flag to indicate that node may be destroyed.
(This protection doesn't work, and it didn't before. Must be redesigned.)
- Increment ngt_unit atomically, removing mutex.
- Acquire Giant, when executing ngt_start() from netgraph context.
- Acquire Giant, when {,de}registering line discipline.
- Uncomment forcing queue mode on peers hook, since this is reasonable.
- Force queue mode on our hook, to avoid acquiring Giant when coming from
network stack. We may already hold some mutexes at this point.
Cleanups:
- Use callout_pending() instead of our own flag.
- Remove spl(9) calls. Now we can use return() instead of ERROUT().
style(9):
- Sort includes.
- Sparse initializer for struct linesw.
- Remove some empty lines, sort declarations.

- Use foo(void) instead of foo().
- Use static where applicable.
- Apply more const's when passing parameters
- signed/unsigned madness
- Avoid namespace collision by adding underscores.
- For 64-bit architectures, use %zx instead of %x
when necessary.
- When storing constants, use const instead of
variable.
- Bump WARNS?= from 2 to 6
of len in tcp_output(), in the case where the FIN has already been
transmitted. The mis-computation of len is because of a gcc
optimization issue, which this change works around.

interrupt is wired up to all the I/O APICs in the system. If the system
has only one I/O APIC, then just act as if the entry specified that APIC.
We still don't try to handle global entries in a system with multiple I/O
APICs.

errno can be tampered potentially by nested signal handle.
Now all error codes are returned in negative value, positive value are
reserved for future expansion.
