In addition to the base snapshot functionality, this will likely entail adding
extra logic to handle edge cases which were formerly not possible, such as
creating then destroying a snapshot in the same transaction sync.

Every time we want to unmount a snapshot (happens during snapshot deletion or
renaming) we unnecessarily iterate through all the mountpoints in the VFS layer
(see zfs_get_vfs).
Ideally we would just put a hold on the snapshot and access its respective VFS

FreeBSD note: I added a FreeBSD specific function getzfsvfs_ref() which
is like getzfsvfs() but returns a filesystem referenced, not busied.
We want a busied filesystem in most cases, because we access its private
data and, thus, we need to prevent the filesystem from being unmounted
and its private data destroyed. But in some cases we can either get
away with just a referenced filesystem or we must not busy the
filesystem. Unmounting the filesystem is one of such cases.

This should eliminate the recently-grown build warnings about multiple

The existing ti_pruss driver for the PRUSS Hardware provided by the AM335x
ARM CPU has basic interrupt capabilities. This updated driver provides some
more options:
- Sysctl based configuration for the interrupts (for some examples, see the
test plan in the phabricator review cited below).
- A device file (/dev/pruss0.irqN) for each enabled interrupt. This file
can be read and the device blocks if no irq has happened or returns an
uint64_t timestamp based on nanouptime().
- Each interrupt device file provides kqueue-based event notification,
blocking read(), or select().

The goal is to use the upstream DTBs as a replacement for our custom one.
This is now possible with these changes.
Additionally, as the RPI firmware automatically chooses the right DTB for
us, this would allow to have one common armv6 kernel for RPI0 and RPI1

not extraneous in the TCP Fast Open (TFO) passive-open case. In the
TFO passive-open case, syncache_socket() is being called during
processing of a TFO SYN bearing a valid cookie, and a call to
soisconnected() is required in order to allow the application to
immediately consume any data delivered in the SYN and to have a chance
to generate response data to accompany the SYN-ACK. The removal of
this call to soisconnected() effectively converted all TFO passive
opens to having the same RTT cost as a standard 3WHS.
This commit adds a call to soisconnected() to syncache_tfo_expand() so
that it is only in the TFO passive-open path, thereby restoring TFO
passve-open RTT performance and preserving the non-TFO connection-rate
performance gains realized by r307966.

common case where it's needed -- a write followed by a read to the same slave.
The i2c controller in this chip only performs complete transfers, it does
not provide control over start/repeat-start/stop operations on the bus.
Thus, we have gotten a full stop/start sequence rather than a repeat-start
when doing a typical i2c slave access of "write address, read data". Some
i2c slave devices require a repeat-start to work correctly.
These changes cause the controller to do a repeat-start by pre-staging the
read parameters in the controller registers immediate after the controller
has latched the values for the initial write operation, but before any
bytes are actually written. With the values pre-staged, when the write
portion of the transfer completes, the state machine in the silicon sees
a new start operation already staged and that causes it to perform a
repeat-start. The key to tricking the buggy hardware into doing this is
to avoid prefilling any output data in the transmit FIFO so that it is
possible to catch the silicon in the state where transmit values are
latched but the transmit isn't completed yet.

Remove the common but not functional attempt to prevent parallel
accesses by file descriptors by blocking more than one open. Either
threads in one process, or forked siblings, or file descriptors passed
over unix domain sockets all allow to execute parallel requests once
one fd is opened. Since ioctl handler uses smbus_request_bus() to
take the bus ownership, the correct mechanism establishes exclusive
access already.

Previously, uiomove_object_page() would maintain LRU by requeuing the
accessed page. This involves acquiring one of the heavily contended page
queue locks. Moreover, it is unnecessarily expensive for pages in the
active queue.
As of r254304 the page daemon continually performs a slow scan of the
active queue, with the effect that unreferenced pages are gradually
moved to the inactive queue, from which they can be reclaimed. Prior to
that revision, the active queue was scanned only during shortages of
free and inactive pages, meaning that unreferenced pages could get
"stuck" in the queue. Thus, tmpfs was required to use the inactive queue
and requeue pages in order to maintain LRU. Now that this is no longer
the case, tmpfs I/O operations can use the active queue and avoid the
page queue locks in most cases, instead setting PGA_REFERENCED on
referenced pages to provide pseudo-LRU.
