The commit uses heuristics to determine whether a PR is behavioral:
It runs "quick" CI (i.e., only use sanity.run on fewer OSes)
if (explicitly requested by user):
- the *last* commit message contains a line 'ZFS-CI-Type: quick',
or if (by heuristics):
- the files changed are not in the list of specified directory, and

META lists the maximum kernel version we consider to be fully supported.
However, we don't enforce this.
Sometimes we ship experimental patches for a newer kernel than we're
ready to support or, less often, we compile just fine against a newer
kernel. Invariably, something doesn't quite work properly, and it's
difficult for users to understand that they're actually running against
a kernel that we're not yet ready to support.
This commit tries to improve this situation. First, it simply enforces
Linux-Maximum, by having configure bail out if you try to compile
against a newer version that.
Then, it adds the --enable-linux-experimental switch to configure. When
supplied, this disables enforcing the maximum version, allowing the user
to attempt to build against a kernel with version higher than
Linux-Maximum.
Finally, if the switch is supplied _and_ configure is run against a
higher kernel version, it shows a big warning message when configure
finishes, and defines HAVE_LINUX_EXPERIMENTAL for the build. This allows
us to add code to modify runtime behaviour as well.

At least FreeBSD has a limit of 256 simultaneous AIO requests per
process. Attempt to issue more results in EAGAIN errors. Since we
issue 4 requests per disk/partition from 2xCPUs threads, it is
quite easy to reach that limit on large systems, that results in
random pool import failures. It annoyed me for quite a while on
a system with 64 CPUs and 70+ partitioned disks.
This patch from one side limits the number of threads to avoid the
error, while from another should softly fall back to sync reads in
case of error. It takes into account _SC_AIO_MAX as a system-wide
AIO limit and _SC_AIO_LISTIO_MAX as a closest value to per-process
limit. The last not exactly right, but it is the best I found.

- at least one saved sector.
Old 12.5% threshold is left to minimize affect
on existing user expectations of CPU utilization.
If data wasn't compressed - it will be saved as
ZIO_COMPRESS_OFF, so if we really need to recompress
data without ashift info and check anything -
we can just compress it with zero threshold.

Specializing cityhash4 on 32-bit architectures can reduce the size
of stack frames as well as instruction count. This is a tiny but
useful optimization, since some callers invoke it frequently.
When specializing into 1/2/3/4-arg versions, the stack usage
(in bytes) on some 32-bit arches are listed as follows:
- x86: 32, 32, 32, 40
- arm-v7a: 20, 20, 28, 36
- riscv: 0, 0, 0, 16
- power: 16, 16, 16, 32
- mipsel: 8, 8, 8, 24
And each actual argument (even if passing 0) contributes evenly
to the number of multiplication instructions generated:
- x86: 9, 12, 15 ,18
- arm-v7a: 6, 8, 10, 12
- riscv / power: 12, 18, 20, 24
- mipsel: 9, 12, 15, 19
On 64-bit architectures, the tendencies are similar. But both stack
sizes and instruction counts are significantly smaller thus negligible.
