ext2fs_reload() is still missing locking from not merging other changes
to ffs_reload(), but none of these is related to recent locking changes.
but can be enabled by setting hw.atm.hatmN.mpsafe in the kernel
environment to a non-zero value before loading the driver. When
the problems with network MPSAFEty have been sorted out this will
be removed and the driver will default to MPSAFE.
We put them directly onto the free list instead of calling the
external mbuf free routine (that routine would have cleaned the flag).
This fixes a bug which manifests itself in falsely reporting a lot of used
buffers when configuring the interface down.
conservative lock. The problem with the lock-less algorithm is that
it suffers from the ABA problem. Running an application with funnels
a couple of 100kpkts/s through the netgraph system on a dual CPU system
with MPSAFE drivers will panic almost immediatly with the old algorithm.
It may be possible to eliminate the contention between threads that insert
free items into the list and those that get free items by using the
Michael/Scott queue algorithm that has two locks.
- check for encryption/authentication key together with algorithm.
- warned if a deprecated encryption algorithm (that includes "simple")
is specified.
- changed the syntax how to define a policy of a ICMPv6 type and/or a
code, like spdadd ::/0 ::/0 icmp6 134,0 -P out none;
- random cleanup in parser.
- use yyfatal, or return -1 after yyerror.
- deal with strdup() failure.
- permit scope notation in policy string (-P
esp/tunnel/foo%scope-bar%scope/use)
- simplify /prefix and [port].
- g/c some unused symbols.

- fixed a length of the sadb extension in the case of pfkey_send_x5().
- used getprotobynumber() for printing a upper layer protocol name.
- modified the output format against the change of the setkey syntax
about a icmp6 type/code.
- don't enumerate reserved fields. use memset.

Introduce two new macros MNT_ILOCK(mp)/MNT_IUNLOCK(mp) to
operate on this mutex transparently.
Eventually new mutex will be protecting more fields in
struct mount, not only vnode list.

That change was intended to support vmware3, but
wantrem parameter is useless because vmware3 uses SYSV shared memory
to talk with X server and X server is native application.
The patch worked because check for wantrem was not valid
(wantrem and SHMSEG_REMOVED was never checked for SHMSEG_ALLOCATED segments).
Add kern.ipc.shm_allow_removed (integer, rw) sysctl (default 0) which when set
to 1 allows to return removed segments in
shm_find_segment_by_shmid() and shm_find_segment_by_shmidx().

the amd64 implementation of the pcpu macros is even more verbose than on
i386 and that causes gcc to way overestimate the complexity of this
2-instruction macro. The other platforms can probably lower their
default values.

Aside from the POSIX requirements for pthread_atfork(), when
fork()ing, take the malloc lock to keep malloc state consistent

(libthr, libpthread) can now have threads running while another
thread calls fork(). In this case, it is possible for malloc
to be left in an inconsistent state in the child. Our thread
libraries, libpthread in particular, need to use malloc internally
after a fork (in the child).
