Make GEOM provider names starting with "/dev/" acceptable as well as their
"raw" names. While there, change the formatting of extended MSDOS partitions
so that the dot (".") is not used to separate two numbers (which kind of
looks like the whole is a decimal number). Use "+" instead, which also
hints that the second part of the name is the offset from the start of
the partition in the first part of the name. Also change the offset from
decimal to hexadecimal notation, simply for aesthetic reasons and future
compatibility.
GEOM_PART is the default in 8-CURRENT but not yet in 7-STABLE so this

Introduce a number of changes to the MROUTING code.
This is purely a forwarding plane cleanup; no control plane
code is involved.
Summary:
* Split IPv4 and IPv6 MROUTING support. The static compile-time
kernel option remains the same, however, the modules may now
be built for IPv4 and IPv6 separately as ip_mroute_mod and
ip6_mroute_mod.
* Clean up the IPv4 multicast forwarding code to use BSD queue
and hash table constructs. Don't build our own timer abstractions
when ratecheck() and timevalclear() etc will do.
* Expose the multicast forwarding cache (MFC) and virtual interface
table (VIF) as sysctls, to reduce netstat's dependence on libkvm
for this information for running kernels.
* bandwidth meters however still require libkvm.
* Make the MFC hash table size a boot/load-time tunable ULONG,
net.inet.ip.mfchashsize (defaults to 256).
* Remove unused members from struct vif and struct mfc.
* Kill RSVP support, as no current RSVP implementation uses it.
These stubs could be moved to raw_ip.c.
* Don't share locks or initialization between IPv4 and IPv6.
* Don't use a static struct route_in6 in ip6_mroute.c.
The v6 code is still using a cached struct route_in6, this is
moved to mif6 for the time being.
* More cleanup remains to be merged from ip_mroute.c to ip6_mroute.c.
v4 path tested using ports/net/mcast-tools.
v6 changes are mostly mechanical locking and *have not* been tested.
As these changes partially break some kernel ABIs, they will not
be MFCed. There is a lot more work to be done here.

The zfs_get_xattrdir() function is used to find the extended attribute
directory for a znode. When the directory already exists, it returns a
referenced but unlocked vnode. When a directory does not yet exist, it
calls zfs_make_xattrdir() to create a new one. zfs_make_xattrdir() returns
the vnode both referenced and and locked and zfs_get_xattrdir() was leaking
this vnode lock to its callers. Fix this by dropping the vnode lock if
zfs_make_xattrdir() successfully creates a new extended attribute

Deal with the case where ifma_protospec may be NULL, during
any IPv4 multicast operations which reference it.
There is a potential race because ifma_protospec is set to NULL
when we discover the underlying ifnet has gone away. This write
is not covered by the IF_ADDR_LOCK, and it's difficult to widen
its scope without making it a recursive lock. It isn't clear why
this manifests more quickly with 802.11 interfaces, but does not
seem to manifest at all with wired interfaces.
With this change, the 802.11 related panics reported by sam@
and cokane@ should go away. It is not the right fix, that requires
more thought before 8.0.

Fix two issues with bufdaemon, often causing the processes to hang in
the "nbufkv" sleep.
First, ffs background cg group block write requests a new buffer for
the shadow copy. When ffs_bufwrite() is called from the bufdaemon due
to buffers shortage, requesting the buffer deadlock bufdaemon.
Introduce a new flag for getnewbuf(), GB_NOWAIT_BD, to request getblk
to not block while allocating the buffer, and return failure
instead. Add a flag argument to the geteblk to allow to pass the flags
to getblk(). Do not repeat the getnewbuf() call from geteblk if buffer
allocation failed and either GB_NOWAIT_BD is specified, or geteblk()
is called from bufdaemon (or its helper, see below). In
ffs_bufwrite(), fall back to synchronous cg block write if shadow
block allocation failed.
Since r107847, buffer write assumes that vnode owning the buffer is
locked. The second problem is that buffer cache may accumulate many
buffers belonging to limited number of vnodes. With such workload,
quite often threads that own the mentioned vnodes locks are trying to
read another block from the vnodes, and, due to buffer cache
exhaustion, are asking bufdaemon for help. Bufdaemon is unable to make
any substantial progress because the vnodes are locked.
Allow the threads owning vnode locks to help the bufdaemon by doing
the flush pass over the buffer cache before getnewbuf() is going to
uninterruptible sleep. Move the flushing code from buf_daemon() to new
helper function buf_do_flush(), that is called from getnewbuf(). The
number of buffers flushed by single call to buf_do_flush() from
getnewbuf() is limited by new sysctl vfs.flushbufqtarget. Prevent
recursive calls to buf_do_flush() by marking the bufdaemon and threads
that temporarily help bufdaemon by TDP_BUFNEED flag.
