- Remove hardcoded uid, gid, mode from struct pfs_node; make pfs_getattr()
smart enough to get it right most of the time, and allow for callbacks
to handle the remaining cases. Rework the definition macros to match.
- Add lots of (conditional) debugging output.
- Fix a long-standing bug inherited from procfs: don't pretend to be a
read-only file system. Instead, return EOPNOTSUPP for operations we
truly can't support and allow others to fail silently. In particular,
pfs_lookup() now treats CREATE as LOOKUP. This may need more work.
- In pfs_lookup(), if the parent node is process-dependent, check that
the process in question still exists.
- Implement pfs_open() - its only current function is to check that the
process opening the file can see the process it belongs to.
- Finish adding support for writeable nodes.
- Bump module version number.
- Introduce lots of new bugs.

Move code to build include and libraries in a separate function,
so we can use the verbose flag for that.
Chang ownership of some directories so more of the build process
(namely, builds of include and libs) can be run without root
permission (we still depend on root permission to mount a memory
filesystem).
allow to limit the prototype quota distribution (-p)
to a single filesystem. Useful when initializing

next to equivalent m_len adjustments. Move the nfsm_subs.h macros
into groups depending on which phase they are used in, since that
affects the error recovery requirements. Collect some of the common error
checking into a single macro as preparation for unwinding some more.
Have nfs_rephead return a value instead of secretly modifying args.
Remove some unused function arguments that were being passed around.
Clarify nfsm_reply()'s error handling (I hope).

While here, redefine the second entry for setpgid() so that we
don't need a stub. This is achieved by giving the second instance
the type NODEF.

done. This differs from type NOPROTO in that NOPROTO adds a
definition to syscall.h besides adding a sysent. A syscall can
now have multiple entries without conflict. Note that the

SysKonnect SK-9D21 and SK-9D41, and the built-in gigE NICs on
Dell PowerEdge 2550 servers. The latter configuration hauls ass:
preliminary measurements show TCP speeds of over 900Mbps using
only normal size frames.
TCP/IP checksum offload, jumbo frames and VLAN tag insertion/stripping
are supported, as well as interrupt moderation.
Still need to fix autonegotiation support for 1000baseSX NICs, but
beyond that, driver is pretty solid.
+ implement "limit" rules, which permit to limit the number of sessions
between certain host pairs (according to masks). These are a special
type of stateful rules, which might be of interest in some cases.
See the ipfw manpage for details.
+ merge the list pointers and ipfw rule descriptors in the kernel, so
the code is smaller, faster and more readable. This patch basically
consists in replacing "foo->rule->bar" with "rule->bar" all over
the place.

is required by some firmware like EFI boot managers (at least on

RFC2347; a generic tftp option extension.

the current interrupt thread routines will guarantee the condition this is
checking for at a higher level but inthand_add() and inthand_remove() as
they currently exist don't satisfy this condition. (Which does need to be
fixed but which will take a bit more work.) This fixes shared interrupts.
