Currently the point of -L option in zdb is to disable leak
tracing and the loading of space maps because they are expensive,
yet still do leak detection in terms of space. Unfortunately,
there is a scenario where this is a lie. If we are using zdb -L
on a pool where a vdev is being removed, zdb_claim_removing()
will open the metaslab space maps of that device.
This patch makes it so zdb -L skips leak detection altogether
and ensures that no space maps are loaded.

= Old behavior
For vdev sizes 100GB to 50TB we keep ~200 metaslabs per
vdev and the metaslab size grows from 512MB to 256GB.
For vdev's bigger than that we start increasing the
number of metaslabs until we hit the 128K limit.
= New Behavior
For vdev sizes 100GB to 3TB we keep ~200 metaslabs per
vdev and the metaslab size grows from 512MB to 16GB.
For vdev's bigger than that we start increasing the
number of metaslabs until we hit the 128K limit.
= Reasoning
The old behavior makes metaslabs grow in size when
the vdev range is between 3TB (ms_size 16GB) and
32PB (ms_size 256GB). Even though keeping the number
of metaslabs is good in terms of potential number of
I/Os per TXG, these bigger metaslabs take longer
to be loaded and after they are loaded they can
take up a lot of memory because of their range trees.
This change tries to put a boundary in memory and
loading time for the specific range of vdev sizes.

By design ztest will never inject non-repairable damage in to the
pool. Update the ztest_scrub() test case such that it waits for
the scrub to complete and verifies the pool is always repairable.
After enabling scrub verification two scenarios were encountered
which are the result of how ztest manages failure injection.
The first case is straight forward and pertains to detaching a
mirror vdev. In this case, the pool must always be scrubbed prior
the detach. Failure to do so can potentially lock in previously
repairable data corruption by removing all good copies of a block
leaving only damaged ones.
The second is a little more subtle. The child/offset selection
logic in ztest_fault_inject() depends on the calculated number of
leaves always remaining constant between injection passes. This
is true within a single execution of ztest, but when using zloop.sh
random values are selected for each restart. Therefore, when ztest
imports an existing pool it must be scrubbed before failure injection
can be safely enabled. Otherwise it is possible that it will inject
non-repairable damage.

The ztest_ddt_repair() test is designed inflict damage to the
ddt which can be repairable by a scrub. Unfortunately, this
repair logic was broken at some point and it went undetected.
This issue is not specific to ztest, but thankfully this extra
redundancy is rarely enabled and even more rarely needed.
The root cause was identified to be the ddt_bp_create()
function called by dsl_scan_ddt_entry() which did not set the
dedup bit of the generated block pointer.
The consequence of this was that the ZIO_DDT_READ_PIPELINE was
never enabled for the block pointer during the scrub, and the
dedup ditto repair logic was never run. Note that for demand
reads which don't rely on ddt_bp_create() the required pipeline
stages would be enabled and the repair performed.
This was resolved by unconditionally setting the dedup bit in
ddt_bp_create(). This way all codes paths which may need to
perform a repair from a block pointer generated from the dtt
entry will be able too. The only exception is that the dedup
bit is cleared in ddt_phys_free() which is required to avoid
leaking space.

Increase the default allowed number of reconstruction attempts.
There's not an exact right number for this setting. It needs
to be set large enough to cover any realistic failure scenarios
and small enough to avoid stalling the IO pipeline and invoking
the dead man detection.
The current value of 256 was empirically determined to be too
low based on multi-day runs of ztest. The fault injection code
would inject more damage than could be reconstructed given the
relatively small number of attempts. However, in all observed
cases the block could be reconstructed using a slightly higher
limit.
Based on local testing increasing the default value to 4096 was
determined to strike the best balance. Checking all combinations
takes less than 10s in the worst case, and has so far eliminated
the vast majority of false positives detected by ztest. This
delay is roughly on par with how long retries may be performed
to a misbehaving HDD and was deemed to be reasonable. Better to
err on the side of a brief delay rather than fail to reconstruct
the data.
Lastly, the -Y flag has been added to zdb to make it easy to try all
possible combinations when performing split block reconstruction.
For badly damaged blocks with 18 splits, they can be fully enumerated
within a few minutes. This has been done to ensure permanent errors
are never incorrectly reported when ztest verifies the pool with zdb.

The implementation of 'zfs remap' has proven to be problematic since
it modifies the objset (but not its logical contents) by dirtying
metadata without owning it. The consequence of which is that
dmu_objset_remap_indirects() is vulnerable to certain races.
For example, if we are in the middle of receiving into the filesystem
while it is being remapped. Then it is possible we could evict the
objset when the receive completes (see dsl_dataset_clone_swap_sync_impl,
or dmu_recv_end_sync), but dmu_objset_remap_indirects() may be still
using the objset. The result of which would be a panic.
Extended runs of ztest(8) have exposed other possible races which
can occur when using 'zfs remap'. Several of these have been fixed
but there may be others which have not yet been encountered and
diagnosed.
Furthermore, the ability to manually remap a filesystem is no longer
particularly useful now that the removal code can map large chunks.
Coupled with the fact that explaining what this command does and why
it may be useful requires a detailed understanding of the internals
of device removal. These are details users should not be bothered
with.
Therefore, the 'zfs remap' command is being disabled but not entirely
removed. It may be removed in the future or potentially reworked
to address the issues described above. Since 'zfs remap' has never
been part of a tagged release its removal is expected to have
minimal impact.
The ZTS tests have been updated to continue to exercise the command
to prevent atrophy, but it has been removed entirely from ztest(8).

zpool status testpool # Will show 0 errors, which is wrong
sudo zpool offline testpool /tmp/a
sudo zpool scrub testpool
zpool status testpool # Will show errors on /tmp/c,
# which should've already been fixed
FreeBSD head is partially affected: the first scrub will detect
some errors, but the second scrub will detect more. This same
test was run on Linux before applying the fix and the FreeBSD

since it has the same X, it's files get inadvertently removed
by fc28's uninstall.
%postun X.fc28
This patch updates %preun X.fc28 to see if we're upgrading or
uninstalling. If we're uninstalling, then remove our files. If we're
upgrading then do nothing, since will know dkms will have already
removed our files in %post X.fc29.
Note that since this fixes the %preun step, it's effect isn't going
to be noticed immediately. It will only be seen when packages
with this fix are upgraded to a newer version.

There's not really a reason to keep the subject length so short,
since the reason to make it this short was for making nice renders
of a summary list of the git log. With 72 characters, this still
works out fine, so let's just raise it to that so that it's easier
to give slightly more descriptive change summaries.
