The bound check condition should always be met because we selected
`set_basic` as our encoding type. But that code is very far away, so
assert it is true so if it is ever false we can catch it, and add a

When reviewing Clang Static Analyzer reports against a branch that had
experimental header changes based on the Coverity model file to inform
it that KM_SLEEP allocations cannot return NULL, I found a report saying
that a KM_PUSHPAGE allocation returned NULL. The actual implementation
does not return NULL unless KM_NOSLEEP has been passed, so we backport
the correction from the experimental header changes to the Coverity

svb is declared on the stack. We then set parts of svb.svb_dva with
DVA_SET_VDEV(), DVA_SET_OFFSET() and DVA_SET_ASIZE(). However, the DVA
contains other fields for pad, GRID and G. When setting the fields we
use, we technically read uninitialized bits from the fields we do not
use. This makes Coverity and Clang's Static Analyzer complain.
Presumably, other static analyzers might complain too.
There is no real bug here, but we are still technically reading
undefined data and unless we stop doing that, static analyzers will
complain about it in perpetuum and this could obscure real issues. We
silence the static analyzer complaints by using a 0 struct initializer.

There was the series from me a year ago which fixed most of the
callback vs implementation prototype mismatches. It was based on
running the CFI-enabled kernel (in permissive mode -- warning
instead of panic) and performing a full ZTS cycle, and then fixing
all of the problems caught by CFI.
Now, Clang 16-dev has new warning flag, -Wcast-function-type-strict,
which detect such mismatches at compile-time. It allows to find the
remaining issues missed by the first series.
There are only two of them left: one for the

The fix is easy, since they are not used anywhere else.

These `sprintf()` calls are used repeatedly to write to a buffer. There
is no protection against overflow other than reviewers explicitly
checking to see if the buffers are big enough. However, such issues are
easily missed during review and when they are missed, we would rather
stop printing rather than have a buffer overflow, so we convert these
functions to use `kmem_scnprintf()`. The Linux kernel provides an entire
page for module parameters, so we are safe to write up to PAGE_SIZE.
Removing `sprintf()` from these functions removes the last instances of
`sprintf()` usage in our platform-independent kernel code. This improves
XNU kernel compatibility because the XNU kernel does not support
(removed support for?) `sprintf()`.

with further adjustment based on ghost lists size/hit. However, in
current code both arc_adapt() and arc_get_data_impl() aggressively
grow arc_p until arc_c is reached, causing unneeded pressure on
MFU and greatly reducing its scan-resistance until ghost list
adjustments kick in.
This patch restores the original behavior of initially having arc_p
as 1/2 of total ARC, without preventing MRU to use up to 100% total

transformation to happen through zfs send, allowing it to be done

A new zstream command is added that decompresses WRITE records and
then recompresses them with a provided algorithm, and then re-emits
