We attempt to remove an existing SA xattr when setting a dir xattr, but
this only makes sense if the znode has been upgraded to the SA format.
Otherwise, we will hit an assert in zfs_sa_get_xattr.
Make sure this is an SA znode before attempting to remove the SA xattr.

It turns out that layouts of union bitfields are a pain, and the

Switch everyone over to the LE layout, and add compatibility code

KTLS OCF support was originally targeted at software backends that
used host CPU cycles to encrypt TLS records. As a result, each KTLS
worker thread queued a single TLS record at a time and waited for it
to be encrypted before processing another TLS record. This works well
for software backends but limits throughput on OCF drivers for
coprocessors that support asynchronous operation such as qat(4) or
ccr(4). This change uses an alternate function (ktls_encrypt_async)
when encrypt TLS records via a coprocessor. This function queues TLS
records for encryption and returns. It defers the work done after a
TLS record has been encrypted (such as marking the mbufs ready) to a
callback invoked asynchronously by the coprocessor driver when a
record has been encrypted.
- Add a struct ktls_ocf_state that holds the per-request state stored
on the stack for synchronous requests. Asynchronous requests malloc
this structure while synchronous requests continue to allocate this
structure on the stack.
- Add a ktls_encrypt_async() variant of ktls_encrypt() which does not
perform request completion after dispatching a request to OCF.
Instead, the ktls_ocf backends invoke ktls_encrypt_cb() when a TLS
record request completes for an asynchronous request.
- Flag AEAD software TLS sessions as async if the backend driver
selected by OCF is an async driver.
- Pull code to create and dispatch an OCF request out of
ktls_encrypt() into a new ktls_encrypt_one() function used by both
ktls_encrypt() and ktls_encrypt_async().
- Pull code to "finish" the VM page shuffling for a file-backed TLS
record into a helper function ktls_finish_noanon() used by both
ktls_encrypt() and ktls_encrypt_cb().

This problem of undefined behavior was also reported to acpica by @cem
in 2018: https://github.com/acpica/acpica/issues/407, but it seems there
was never any fix committed for it upstream.
Instead fix these locally, for ACPI_TO_INTEGER by simply casting the
incoming pointer to ACPI_SIZE (which corresponds roughly to uintptr_t
and size_t), and for ACPI_OFFSET by reusing our __offsetof definition
from sys/cdefs.h.

It is always a good idea. In one case, attempting to allocate N+1 PMCs

allocate from the next class in the list. Without this validation, this

When executing strip(1), '--' is passed as an argument to explicitly

support this however, so setting XSTRIPBIN=llvm-strip results in an

commandline-compatible with FreeBSD's strip(1), so just use the
documented argument format that is common to both.

This is because the expression first casts start_info->modlist_paddr to
struct hvm_modlist_entry * (via vmpaddr_t), and *then* adds KERNBASE,
which is then interpreted as KERNBASE * sizeof(struct
hvm_modlist_entry).
Instead, parenthesize the addition to get the intended result, and cast
it to struct hvm_modlist_entry * afterwards. Also remove the cast to
vmpaddr_t since it is not necessary.

The ZTS block_device_wait helper function should use -e when waiting
for a file to appear since it will be either a block special device
or a symlink. This didn't cause any failures but when a device path
was specified the function would wait longer than needed.
Additionally update the most flakey test cases to pass the file path
to block_device_wait to try and improve the test reliability. The
udev behavior on Fedora in particular can result in frequent false
positives.
