In the past there have been times when we need to generate new RPMs
for an existing ZFS release. Typically this happens when a new RHEL
version comes out and the kernel symbols no longer match. To get
users to auto-update we just bump the patch number. For example, we
had to create zfs-2.1.13-1 for EL8.8 and zfs-2.1.13-2 for EL8.9.
This commit adds an optional patch level text box to the github
package builder runner.
In addition, this commit also uses `hostnamectl` instead of `hostname`
for F42+ compatibility, if available.

In syncing mode, zfs_putpages() would put the entire range of pages onto
the ZIL, then return VM_PAGER_OK for each page to the kernel. However,
an associated zil_commit() or txg sync had not happened at this point,
so the write may not actually be on disk.
So, we rework that case to use a ZIL commit callback, and do the
post-write work of undirtying the page and signaling completion there.
We return VM_PAGER_PEND to the kernel instead so it knows that we will
take care of it.
The original version of this (238eab7dc1) copied the Linux model and did
the cleanup in a ZIL callback for both async and sync. This was a
mistake, as FreeBSD does not have a separate "busy for writeback" flag
like Linux which keeps the page usable. The full sbusy flag locks the
entire page out until the itx callback fires, which for async is after
txg sync, which could be literal seconds in the future.
For the async case, the data is already on the DMU and the in-memory
ZIL, which is sufficient for async writeback, so the old method of
logging it without a callback, undirtying the page and returning is more
than sufficient and reclaims that lost performance.

Systems with a large number of CPU cores (192+) may trigger the large

On Linux this results in a call to kvalloc() which will alloc vmem

On FreeBSD both vmem_alloc and kmem_alloc internally use the same

03987f71e3 (#16069) added a workaround to get the blk-mq hardware
context for older kernels that don't cache it in the struct request.
However, this workaround appears to be incomplete.
In 4.19, the rq data context is optional. If its not initialised, then
the cached rq->cpu will be -1, and so using it to index into mq_map
causes a crash.
Given that the upstream 4.19 is now in extended LTS and rarely seen,
RHEL8 4.18+ has long carried "modern" blk-mq support, and the cached
hardware context has been available since 5.1, I'm not going to huge
lengths to get queue selection correct for the very few people that are
likely to feel it. To that end, we simply call raw_smp_processor_id() to
get a valid CPU id and use that instead.

The redundant_metadata setting in ZFS allows users to trade resilience
for performance and space savings. This applies to all data and metadata
blocks in zfs, with one exception: gang blocks. Gang blocks currently
just take the copies property of the IO being ganged and, if it's 1,
sets it to 2. This means that we always make at least two copies of a
gang header, which is good for resilience. However, if the users care
more about performance than resilience, their gang blocks will be even
more of a penalty than usual.
We add logic to calculate the number of gang headers copies directly,
and store it as a separate IO property. This is stored in the IO
properties and not calculated when we decide to gang because by that
point we may not have easy access to the relevant information about what
kind of block is being stored. We also check the redundant_metadata
property when doing so, and use that to decide whether to store an extra
copy of the gang headers, compared to the underlying blocks.
