data in an mbuf, use M_WRITABLE() instead of a direct test of M_EXT;
the latter both unnecessarily exposes mbuf-allocator internals in the
protocol stack and is also insufficient to catch all cases of
non-writability.
(NB: m_pullup() does not actually guarantee that a writable mbuf is
returned, so further refinement of all of these code paths continues to
be required.)

Make this subcommand less FC-specific, reporting target and port addresses
in more generic way. Also make it report list of connected initiators in
unified way, working for both FC and iSCSI, and potentially others.

- Add a mutex to protect the softc.
- Use callout(9) instead of timeout(9).
- Consolidate duplicated detach routines into a bus-independent detach
routine.
- Add an extra sleep lock flag (MSESC_READING) to prevent other readers
from reading while the first reader is copying data out of sc_bytes[]
via uiomove().
- Use bus_*() instead of bus_space_*().

According the hosts_access(3) man page the hosts_ctl() prototype
should be in tcpd.h. For now, follow other declarations and don't
add the arguments in the prototype.

1. Remove initializer for badstack_sbuf_size; it gets set unconditionally.
2. Remove meaningless comment.
3. Group witness_count and its sysctl together.
4. Fix spacing in for statements (space after for and within condition).
5. Change *all* M_NOWAIT usages in witness_initialize() to M_WAITOK; not
just those that were newly introduced -- the allocation is assumed to
succeed for all allocations.
6. Avoid using uint8_t as the base type in sizeof() expressions; Use the
variable name (w_rmatrix) as much as possible.

Queued async events handling in CAM opened race, that may lead to duplicate
AC_PATH_REGISTERED events delivery during boot. That was not happening
before r272935 because the driver was initialized later. After that change
it started create duplicate ports in CTL.
Target mode operation does not depend on the initiator mode scan process.
This change allows the target driver to attach earlier and receive some
async events (like AC_CONTRACT) that could be lost otherwise.

the value without recompiling the kernel. This is useful when
recompiling is not possible as an immediate solution. When we run out
of witness objects, witness is completely disabled. Not having an
immediate solution can therefore be problematic.

The set of valid options that can be passed to bhyvectl now depends on the
processor type. AMD-specific options are identified by a "--vmcb" or "--avic"
in the option name. Intel-specific options are identified by a "--vmcs" in
the option name.

Such LUNs will be visible to initiators, but return "not ready" status
on media access commands. If backing storage become available later,
`ctladm modify ...` or `service ctld reload` can trigger its reopen.
FreeBSD segfaults on invalid pointers passed to getcwd because it throbs the
address passed in in libc, whereas NetBSD just passes the information off to
the syscall, which allows the kernel to return EFAULT on bad pointers.

compatible with write-locked path. Test for MAP_ENTRY_NOSYNC and set
VPO_NOSYNC for pages with dirty mask zero (this does not exclude a
possibility that the page is dirty, e.g. due to read fault on
writeable mapping and consequent write; the same issue exists in the
slow path).
Use helper vm_fault_dirty() to unify fast and slow path handling of
VPO_NOSYNC and setting the dirty mask.
