When encryption was first added to ZFS, we made a decision to
prevent users from creating unencrypted children of encrypted
datasets. The idea was to prevent users from inadvertently
leaving some of their data unencrypted. However, since the
release of 0.8.0, some legitimate reasons have been brought up
for this behavior to be allowed. This patch simply removes this
limitation from all code paths that had checks for it and updates
the tests accordingly.

For busy ARC situation when arc_size close to arc_c is desired. But
then it is quite likely that aggsum_compare(&arc_size, arc_c) will need
to flush per-CPU buckets to find exact comparison result. Doing that
often in a hot path penalizes whole idea of aggsum usage there, since it
replaces few simple atomic additions with dozens of lock acquisitions.
Replacing aggsum_compare() with aggsum_upper_bound() in code increasing
arc_p when ARC is growing (arc_size < arc_c) according to PMC profiles
allows to save ~5% of CPU time in aggsum code during sequential write
to 12 ZVOLs with 16KB block size on large dual-socket system.
I suppose there some minor arc_p behavior change due to lower precision
of the new code, but I don't think it is a big deal, since it should
affect only very small window in time (aggsum buckets are flushed every
second) and in ARC size (buckets are limited to 10 average ARC blocks
per CPU).

If the zfs_remove_max_segment tunable is changed to be not a multiple of
the sector size, then the device removal code will malfunction and try
to create mappings that are smaller than one sector, leading to a panic.
On debug bits this assertion will fail in spa_vdev_copy_segment():
ASSERT3U(DVA_GET_ASIZE(&dst), ==, size);
On nondebug, the system panics with a stack like:
metaslab_free_concrete()
metaslab_free_impl()
metaslab_free_impl_cb()
vdev_indirect_remap()
free_from_removing_vdev()
metaslab_free_impl()
metaslab_free_dva()
metaslab_free()
Fortunately, the default for zfs_remove_max_segment is 1MB, so this
can't occur by default. We hit it during this test because
removal_remap.ksh changes zfs_remove_max_segment to 1KB. When testing on
4KB-sector disks, we hit the bug.
This change makes the zfs_remove_max_segment tunable more robust,
automatically rounding it up to a multiple of the sector size. We also
turn some key assertions into VERIFY's so that similar bugs would be
caught before they are encoded on disk (and thus avoid a
panic-reboot-loop).

Starting in sync pass 5 (zfs_sync_pass_dont_compress), we disable
compression (including of metadata). Ostensibly this helps the sync
passes to converge (i.e. for a sync pass to not need to allocate
anything because it is 100% overwrites).
However, in practice it increases the average number of sync passes,
because when we turn compression off, a lot of block's size will change
and thus we have to re-allocate (not overwrite) them. It also increases
the number of 128KB allocations (e.g. for indirect blocks and spacemaps)
because these will not be compressed. The 128K allocations are
especially detrimental to performance on highly fragmented systems,
which may have very few free segments of this size, and may need to load
new metaslabs to satisfy 128K allocations.
We should increase zfs_sync_pass_dont_compress. In practice on a highly
fragmented system we see a few 5-pass txg's, a tiny number of 6-pass
txg's, and no txg's with more than 6 passes.

Sometimes the target ARC size is reduced to arc_c_min, which impacts
performance. We've seen this happen as part of the random_reads
performance regression test, where the ARC size is reduced before the
reads test starts which impacts how long it takes for system to reach
good IOPS performance.
We call arc_reduce_target_size when arc_reap_cb_check() returns TRUE,
and arc_available_memory() is less than arc_c>>arc_shrink_shift.
However, arc_available_memory() could easily be low, even when arc_c is
low, because we can have tons of unused bufs in the abd kmem cache. This
would be especially true just after the DMU requests a bunch of stuff be
evicted from the ARC (e.g. due to "zpool export").
To fix this, the ARC should reduce arc_c by the requested amount, not
all the way down to arc_size (or arc_c_min), which can be very small.

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.

use the old callback signature. Also add a check for a `flags` member in
`struct timer_list`, which was added in 4.1-rc8.
Add compatibility shims to `include/spl/sys/timer.h` to allow using the
new timer APIs with the only two caveats being that the callback
argument type must be declared as `spl_timer_list_t` and an explicit
assignment is required to get the timer variable for the `timer_of()`
macro. So the callback would look like this:
```c
__cv_wakeup(spl_timer_list_t t)
{
struct timer_list *tmr = (struct timer_list *)t;
struct thing *parent = from_timer(parent, tmr,
parent_timer_field);
... /* do stuff with parent */

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.
