This issue tracks the port of scrub pause from ZoL: https://github.com/zfsonlinux/zfs/pull/6167
Currently, there is no way to pause a scrub. Pausing may be useful when
the pool is busy with other I/O to preserve bandwidth.
Description
This patch adds the ability to pause and resume scrubbing. This is achieved
by maintaining a persistent on-disk scrub state. While the state is 'paused'
we do not scrub any more blocks. We do however perform regular scan
housekeeping such as freeing async destroyed and deadlist blocks while paused.
If you're testing this change, you probably want to include the patch from #6164
Motivation and Context
Scrub pausing can be an I/O intensive operation and people have been asking
for the ability to pause a scrub for a while. This allows one to preserve scrub
progress while freeing up bandwidth for other I/O.
How Has This Been Tested?
Unit testing and zfs-tests. to the pool. This patch will also include the
patch from https://github.com/zfsonlinux/zfs/ pull/6164 In certain cases
(dsl_scan_sync() is one), we may end up calling

This creates conflicts with FreeBSD variations that may use it. The
usage of the flag M_TOOBIG is limited to iflib queue, thus using
one of M_PROTO flags is fine. There is no need to grab global flag.

In theory this allows to avoid one more expensive doorbell register read
later in some scenarios. But in practice it also significantly increases
packet rate on PLX hardware, that I can't explain yet, possibly work-
arounding some interrupt delays.

compatible string to check if the board is compatible with a given quirk.
It's possible this will be moved later, however as it's currently only used
by the MP code put it there.
So far the only instance of a quirk is when the list of CPUs may be
incorrect. This can happen on virtual machines with a hard coded
devicetree, but where the user may then set the number of CPUs as an
argument. This is the case on the ARM models so include the model specific
compat strings for these, including the spelling mistake found in some of
the OpenplatformPkg dtb files.

Many UEFI variables are UCS2 strings (some NUL terminated, others

Record the file path for boot1.efi as the UEFI environemnt variable
FreeBSDBootVarGUID:Boot1Path. Record the device this came from as
FreeBSDBootVarGUID:Boot1Dev. While later stages of the boot may be
able to guess these values by retrieving UEFIGlobal:BootCurrent and
groveling through the correct UEFIGlobal:BootXXXX, this provides
certanty in the face of behavior from any part of the boot loader
chain that might "guess" what to do next. These env variables are
volatile and will disappear on reboot.

In the FreeBSD UEFI boot protocol, boot1.efi exits back to UEFI if it
can't boot the image for most reasons (so that further items in the
EFI boot manger list can be tried). Rename panic to efi_panic, make it
static and give it an extra status argument. Exit back to UEFI with
that status argument so the next loader can be tried.
Use malloc/free exclusively instead of mixing malloc/free and
AllocatePool/FreePool. The code is smaller.

Print the device that boot1.efi was loaded from. Print the path as
well (since it isn't included in DeviceHandle). Move block where we do
this earlier so all the block handle code is now together.

Make efichar.c routines available to libefi as well as

stand.h vs the normal userland stuff.
o Add File to the mUefiDevicePathLibDevPathFromTextTable table so we
don't include 'File()' in the supposed path name. This happens because
of a possible misfeature in the EDK2 code where any path that's not
recognized is treated as a File() node.
o Convert utf8 input into ucs2 output rather than just copying the
utf8 and hoping for the best (no good comes from that).
o Remove bogus comment about needing to add 1. The dummy array already
is length 1, so that's included in sizeof the struct, so there's no
need to add it.

Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not
ASCII/UTF8. Convert to utf8 and print that when printing File
paths. Also, since File may be at the end of a long device path,
output File() around the path so it doesn't just show up as random
nodes that might accidentally match real node paths names and cause
errors.

The default value for arc_no_grow_shift may not be optimal when using
several GiB ARC. Expose it via sysctl allows users to tune it easily.
Also expose arc_grow_retry via sysctl for the same reason. The default value of
60s might, in case of intensive load, be too long.

This driver supports both NTB-to-NTB and NTB-to-Root Port modes (though
the second with predictable complications on hot-plug and reboot events).
I tested it with PEX 8717 and PEX 8733 chips, but expect it should work
with many other compatible ones too. It supports up to two NT bridges
per chip, each of which can have up to 2 64-bit or 4 32-bit memory windows,
6 or 12 scratchpad registers and 16 doorbells. There are also 4 DMA engines
in those chips, but they are not yet supported.
While there, rename Intel NTB driver from generic ntb_hw(4) to more specific
