Scatter ABD's are allocated from a number of pages. In contrast to
linear ABD's, these pages are disjoint in the kernel's virtual address
space, so they can't be accessed as a contiguous buffer. Therefore
routines that need a linear buffer (e.g. abd_borrow_buf() and friends)
must allocate a separate linear buffer (with zio_buf_alloc()), and copy
the contents of the pages to/from the linear buffer. This can have a
measurable performance overhead on some workloads.
https://github.com/zfsonlinux/zfs/commit/87c25d567fb7969b44c7d8af63990e
("abd_alloc should use scatter for >1K allocations") increased the use
of scatter ABD's, specifically switching 1.5K through 4K (inclusive)
buffers from linear to scatter. For workloads that access blocks whose
compressed sizes are in this range, that commit introduced an additional
copy into the read code path. For example, the
sequential_reads_arc_cached tests in the test suite were reduced by
around 5% (this is doing reads of 8K-logical blocks, compressed to 3K,
which are cached in the ARC).
This commit treats single-chunk scattered buffers as linear buffers,
because they are contiguous in the kernel's virtual address space.
All single-page (4K) ABD's can be represented this way. Some multi-page
ABD's can also be represented this way, if we were able to allocate a
single "chunk" (higher-order "page" which represents a power-of-2 series
of physically-contiguous pages). This is often the case for 2-page (8K)
ABD's.
Representing a single-entry scatter ABD as a linear ABD has the
performance advantage of avoiding the copy (and allocation) in
abd_borrow_buf_copy / abd_return_buf_copy. A performance increase of
around 5% has been observed for ARC-cached reads (of small blocks which
can take advantage of this), fixing the regression introduced by
87c25d567.
Note that this optimization is only possible because all physical memory
is always mapped into the kernel's address space. This is not the case
for HIGHMEM pages, so the optimization can not be made on 32-bit
systems.

We've observed that on some highly fragmented pools, most metaslab
allocations are small (~2-8KB), but there are some large, 128K
allocations. The large allocations are for ZIL blocks. If there is a
lot of fragmentation, the large allocations can be hard to satisfy.
The most common impact of this is that we need to check (and thus load)
lots of metaslabs from the ZIL allocation code path, causing sync writes
to wait for metaslabs to load, which can take a second or more. In the
worst case, we may not be able to satisfy the allocation, in which case
the ZIL will resort to txg_wait_synced() to ensure the change is on
disk.
To provide a workaround for this, this change adds a tunable that can
reduce the size of ZIL blocks.

On large systems, the memory used by loaded metaslabs can become
a concern. While range trees are a fairly efficient data structure,
on heavily fragmented pools they can still consume a significant
amount of memory. This problem is amplified when we fail to unload
metaslabs that we aren't using. Currently, we only unload a metaslab
during metaslab_sync_done; in order for that function to be called
on a given metaslab in a given txg, we have to have dirtied that
metaslab in that txg. If the dirtying was the result of an allocation,
we wouldn't be unloading it (since it wouldn't be 8 txgs since it
was selected), so in effect we only unload a metaslab during txgs
where it's being freed from.
We move the unload logic from sync_done to a new function, and
call that function on all metaslabs in a given vdev during
vdev_sync_done().

Historically while doing performance testing we've noticed that IOPS
can be significantly reduced when all vdevs in the pool are hitting
the zfs_mg_fragmentation_threshold percentage. Specifically in a
hypothetical pool with two vdevs, what can happen is the following:
Vdev A would go above that threshold and only vdev B would be used.
Then vdev B would pass that threshold but vdev A would go below it
(we've been freeing from A to allocate to B). The allocations would
go back and forth utilizing one vdev at a time with IOPS taking a hit.
Empirically, we've seen that our vdev selection for allocations is
good enough that fragmentation increases uniformly across all vdevs
the majority of the time. Thus we set the threshold percentage high
enough to avoid hitting the speed bump on pools that are being pushed
to the edge. We effectively disable its effect in the majority of the
cases but we don't remove (at least for now) just in case we hit any
weird behavior in the future.

The ZFS on-disk format stores each inode's generation ID as a 64
bit number on disk and in-core. However, the Linux kernel's inode
is only a 32 bit number. In most places, the code handles this
correctly, but the cast is missing in zfs_rezget(). For many pools,
this isn't an issue since the generation ID is computed as the
current txg when the inode is created and many pools don't have
more than 2^32 txgs.
For the pools that have more txgs, this issue causes any inode with
a high enough generation number to report IO errors after a call to
"zfs rollback" while holding the file or directory open. This patch
simply adds the missing cast.
