non-legacy mountpoints. It is better to be able to rename such file systems and
let them be mounted in old places until next reboot than using live CD, etc. to
rename with remount.
This is implemented by adding -u option to 'zfs rename'. If file system's
mountpoint property is set to 'legacy' or 'none', there is no need to specify -u.
Update zfs(8) manual page to reflect this addition.

controller which is found on ULi M1563 South Bridge & M1689 Bridge.
These controllers look like a tulip clone.
M5263 controller does not support MII bitbang so use DC_ROM
register to access MII registers. Like other tulip variants, ULi
controller uses a setup frame to configure RX filter and uses new
setup frame format. It's not clear to me whether the controller
supports a hash based multicast filtering so this patch uses 14
perfect multicast filter to filter multicast frames. If number of
multicast addresses is greater than 14, controller is put into a
mode that receives all multicast frames.
Due to lack of access to M5261, this change was not tested with
M5261 but it probably works. Many thanks to Marco who provided
remote access to M5263.

link such that calling dc_setcfg() right after media change would
be meaningless unless controller in question is not Davicom DM9102.
Ideally dc_setcfg() should be called when speed/duplex is resolved
otherwise it would reprogram controller with wrong speed/duplex
information. Because MII status change callback already calls
dc_setcfg() I think calling dc_setcfg() in dc_init_locked() is
wrong. For instance, it would take some time to establish a link
after mii_mediachg(), so blindly calling dc_setcfg() right after
mii_mediachg() will always yield wrong media configuration.
Extend dc_ifmedia_upd() to handle media change and still allow
21143 and Davidcom controllers program speed/duplex regardless of
current resolved speed/duplex of link. In theory 21143 may not need
to call dc_setcfg() right after media change, but leave it as it is
because there are too many variants to test that change. Probably
dc(4) shall need a PHY reset in dc_ifmedia_upd() but it's hard to
verify correctness of the change.
This change reliably makes ULi M5263 establish a link.
While I'm here correctly report media change result. Previously it
always reported a success.
I have some packages that install to / (for whatever reason). Right now we
print entries of the form //path/to/file when listing files (pkg_info -L,
pkg_info -g etc.) This change avoids printing the redundant / .
failure (the getnewvnode cannot return an error). In this case, the
null_insmntque_dtr() already unlocked the reclaimed vnode, so VOP_UNLOCK()
in the nullfs_mount() after null_nodeget() failure is wrong.

It is possible for file systems with 'mountpoint' preperty set to 'legacy'
or 'none' - we don't have to change mount directory for them.
Currently such file systems are unmounted on rename and not even mounted back.
This introduces layering violation, as we need to update 'f_mntfromname'
field in statfs structure related to mountpoint (for the dataset we are
renaming and all its children).
In my opinion it is worth it, as it allow to update FreeBSD in even cleaner
way - in ZFS-only configuration root file system is ZFS file system with
'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs,
we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs),
update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs
and rename it back to system/rootfs while it is mounted as /. Before it was
not possible, because unmounting / was not possible.

of scheduling next run pfsync_bulk_update(), pfsync_bulk_fail()
was scheduled.
This lead to instant 100% state leak after first bulk update
request.
- After above fix, it appeared that pfsync_bulk_update() lacks
locking. To fix this, sc_bulk_tmo callout was converted to an
mtx one. Eventually, all pf/pfsync callouts should be converted
to mtx version, since it isn't possible to stop or drain a
non-mtx callout without risk of race.
- Add comment that callout_stop() in pfsync_clone_destroy() lacks
locking. Since pfsync0 can't be destroyed (yet), let it be here.
The root of problem is re-locking at the end of pfsync_sendout().
Several functions are calling pfsync_sendout() holding pointers
to pf data on stack, and these functions expect this data to be
consistent.
To fix this, the following approach was taken:
- The pfsync_sendout() doesn't call ip_output() directly, but
enqueues the mbuf on sc->sc_ifp's interfaces queue, that
is currently unused. Then pfsync netisr is scheduled. PF_LOCK
isn't dropped in pfsync_sendout().
- The netisr runs through queue and ip_output()s packets
on it.
Apart from fixing race, this also decouples stack, fixing
potential issues, that may happen, when sending pfsync(4)
packets on input path.
