driver_t was supposed to just be a quick hack for 4.x
compatibility. However, it's been documented now as the preferred API
rather than the replacement kobj_class_t. Drop the note about 4.x since
it's clear we're a bit late to retiring its use through the tree with
almost 1500 references to driver_t.

b51f459a20 resulted in a mismerge
due to having to do a remerge because my tree was over a week out of
date. Changes that were made to fix the build were lost in the remerge
resulting in build errors that were fixed a week ago.
First, two of those four checks are unreachable.
Second, I don't believe there should be ">=" instead of ">".

There is a weird limit of AGTIAPI_MAX_DMA_SEGS (128) S/G segments per

can only guess some hardware limitation, but in worst case it means
maximum I/O size of 508KB. Respect it to be safe, rounding to 256KB.

A security feature from c06f087ccb appeared to be a huge bottleneck
under SYN flood. To mitigate that add a sysctl that would make
syncache(4) globally visible, ignoring UID/GID, jail(2) and mac(4)

socket credential for every incoming SYN packet.

This reverts commit 9edaceca81.
It turns out that the Linux client intentionally does an NFSv4.1
RPC with only a Sequence operation in it and with "seqid + 1"
for the slot. This is used to re-synchronize the slot's seqid
and the client expects the NFS4ERR_SEQ_MISORDERED error reply.
As such, revert the patch, so that the server remains RFC5661
compliant.
Initial fib algo implementation was build on a very simple set of
principles w.r.t updates:
1) algorithm is ether able to apply the change synchronously (DIR24-8)
or requires full rebuild (bsearch, lradix).
2) framework falls back to rebuild on every error (memory allocation,
nhg limit, other internal algo errors, etc).
This changes brings the new "intermediate" concept - batched updates.
Algotirhm can indicate that the particular update has to be handled in
batched fashion (FLM_BATCH).
The framework will write this update and other updates to the temporary
buffer instead of pushing them to the algo callback.
Depending on the update rate, the framework will batch 50..1024 ms of updates
and submit them to a different algo callback.
This functionality is handy for the slow-to-rebuild algorithms like DXR.

Clang 12 currently emits this warning for all non-x86 architectures.
While this can result in incorrect code generation (e.g. on AArch64 some
exceptions are not raised as expected), this is a pre-existing issue and
