After the merge of OpenZFS master-9312e0fd1 it has become possible to
import ZFS pools witn an active org.illumos:edonr feature on FreeBSD,
leading to a panic.
In addition, "zpool status" reported all pools without edonr as upgradable
and "zpool upgrade -v" lists edonr in the list of upgradable features.
This is an accepted but not yet included bugfix by upstream.

The manual page lists a bunch of examples, some of which already exist
in this file. Since it's both easier to remember when all examples are
listed in the same location, move examples so they get installed into
/etc/inetd.conf
This also means users won't have to copy-paste, but can simply
uncomment one or more services to use them.
As such, it also becomes necessary to remove the examples from the
manual page, so instead add a note explaining where the previous
examples as well as others may be found.
Cross-references, including to ports, have also been added where
applicable.
The rsync example has lived in the bug tracker for too long,
considering how useful it can situationally be, for example when
backup jobs on client devices are run through periodic(8) weekly.
The microsoft-ds entry is necessary for Windows 10 compatibility
(this can be confirmed with packet capturing, as it is not readily
documented at time of writing).
While here, remove two examples for which compatible daemons could not
be found in ports.

do_jail_attach() now only uses the PD_XXX flags that refer to lock
status, so make sure that something else like PD_KILL doesn't slip
through.
Add a KASSERT() in prison_deref() to catch any further PD_KILL misuse.
The purpose of these checks is to ensure that the address of the
next-level page table page is valid, since nothing is synchronizing with
a concurrent update of the large map and large map PTPs are freed to the
system. However, if PG_PS is set, there is no next level.

In uart_phyp_get(), when the internal buffer is empty, we make a
hypercall to retrieve up to 16 bytes of input data from the
hypervisor. As this is specified to be returned in BE format, we need
to do a 64-bit byte swap on the first and second half of the data.
If the buffer being passed in was insufficient to return the fetched
data, we store the remainder in the internal buffer and use it to
satisfy the following calls to uart_phyp_get() until it is drained.
However, in this case, we were accidentally byteswapping the internal
buffer again.
Move the byteswapping code to just after the hypercall so it only gets
swapped when we're filling the buffer.

We were unlocking the vm object before reading the backing_object field.
In the meantime, the object could be freed and reused. This could cause
us to go off the rails in the object chain traversal, failing to unlock
the rest of the objects in the original chain and corrupting the lock
state of the victim chain.

Even with an absolute offset we want to know the last block the partition

dirtybufthresh is a watermark, slightly below the high watermark for
dirty buffers. When a delayed write is issued, the dirtying thread will
start flushing buffers if the dirtybufthresh watermark is reached. This
helps ensure that the high watermark is not reached, otherwise
performance will degrade as clustering and other optimizations are
disabled (see buf_dirty_count_severe()).
When the buffer cache was partitioned into "domains", the dirtybufthresh
threshold checks were not updated. Fix this.

Previously sendfile would issue a VOP_GETATTR and use the returned size,
i.e., the file size. When paging in file data, sendfile_swapin() will
use the pager to determine whether it needs to zero-fill, most often
because of a hole in a sparse file. An attempt to page in beyond the
end of a file is treated this way, and occurs when the requested page is
past the end of the pager. In other words, both the file size and pager
size were used interchangeably.
With ZFS, updates to the pager and file sizes are not synchronized by
the exclusive vnode lock, at least partially due to its use of
MNTK_SHARED_WRITES. In particular, the pager size is updated after the
file size, so in the presence of a writer concurrently extending the
file, sendfile could incorrectly instantiate "holes" in the page cache
pages backing the file, which manifests as data corruption when reading
the file back from the page cache. The on-disk copy is unaffected.
Fix this by consistently using the pager size when available.
