This allows us to make strong assertions about descriptor address
validity. Additionally, future generations of the ioat(4) hardware will
require contiguous descriptors.

This paves the way for a contiguous descriptor array.
A contiguous descriptor array has the benefit that we can make strong
assertions about whether an address is a valid descriptor or not. The
other benefit is that future generations of I/OAT hardware will require
a contiguous descriptor array anyway. The downside is that after system
boot, big chunks of contiguous memory is much harder to find. So
dynamic scaling after boot is basically impossible.

the vnode lock before incrementing the object's paging-in-progress count.
Now, we increment it before attempting to acquire the vnode lock with
LK_NOWAIT, but we never sleep acquiring the vnode lock while we have the
count incremented.

Before this an earlier writes to a ZVOL opened without FSYNC could get to
ZIL after later writes to the same ZVOL opened with FSYNC. Fix this by
replicating functionality of ZPL (zv_sync_cnt equivalent to z_sync_cnt),
marking all log records sync if anybody opened the ZVOL with FSYNC.

This cleans up a warning when building libm at higher WARNS levels and
makes the intent more clear. By the C standard the values are assigned
to subobject members in order so this change introduces no functional
change. (6.7.9 20)

Also remove the now-redundant error handling that was only for makefs.
This script was run on an older FreeBSD host that lacked efi-on-mbr

Upstream the BUF_TRACKING and FULL_BUF_TRACKING buffer debugging code.
This can be handy in tracking down what code touched hung bios and bufs
last. The full history is especially useful, but adds enough bloat that
it shouldn't be enabled in release builds.
Function names (or arbitrary string constants) are tracked in a
fixed-size ring in bufs. Bios gain a pointer to the upper buf for
tracking. SCSI CCBs gain a pointer to the upper bio for tracking.
