Before Linux 5.3, the filesystem's copy_file_range handler had to signal
back to the kernel that we can't fulfill the request and it should
fallback to a content copy. This is done by returning -EOPNOTSUPP.
This commit converts the EXDEV return from zfs_clone_range to
EOPNOTSUPP, to force the kernel to fallback for all the valid reasons it
might be unable to clone. Without it the copy_file_range() syscall will
return EXDEV to userspace, breaking its semantics.
Add test for copy_file_range fallbacks. copy_file_range should always
fallback to a content copy whenever ZFS can't service the request with
cloning.

test-runner.py orchestrates all of the ZTS executions. The `Cmd` object
manages these process, and its `run` method specifically invokes these
possibly long-running processes, possibly retrying in the event of a
timeout. Since its inception, memory leak detection using the kmemleak
infrastructure [1], and kernel logging [2] have been added to this run
mechanism.
However, the callback to cull a process beyond its timeout threshold,
`kill_cmd`, has evaded modernization by both of these changes. As a
result, this function fails to properly invoke `run`, leading to an
untrapped exception and unreported test failure.
This patch extends `kill_cmd` to receive these kernel devices through
the `options` parameter, and regularizes all the `.run` calls from
`Cmd`, and its subclasses, to accept that parameter.

Implement support for Linux's RENAME_* flags (for renameat2). Aside from
being quite useful for userspace (providing race-free ways to exchange
paths and implement mv --no-clobber), they are used by overlayfs and are
thus required in order to use overlayfs-on-ZFS.
In order for us to represent the new renameat2(2) flags in the ZIL, we
create two new transaction types for the two flags which need
transactional-level support (RENAME_EXCHANGE and RENAME_WHITEOUT).
RENAME_NOREPLACE does not need any ZIL support because we know that if
the operation succeeded before creating the ZIL entry, there was no file
to be clobbered and thus it can be treated as a regular TX_RENAME.

Closes#12923Closes#13671
When scrubbing a raidz/draid pool, which contains a replacing or
sparing mirror with multiple online children, only one child will
be read. This is not normally a serious concern because the DTL
records are used to determine where a good copy of the data is.
As long as the data can be read from one child the mirror vdev
will use it to repair gaps in any of its children. Furthermore,
even if the data which was read is corrupt the raidz code will
detect this and issue its own repair I/O to correct the damage
in the mirror vdev.
However, in the scenario where the DTL is wrong due to silent
data corruption (say due to overwriting one child) and the scrub
happens to read from a child with good data, then the other damaged
mirror child will not be detected nor repaired.
While this is possible for both raidz and draid vdevs, it's most
pronounced when using draid. This is because by default the zed
will sequentially rebuild a draid pool to a distributed spare,
and the distributed spare half of the mirror is always preferred
since it delivers better performance. This means the damaged
half of the mirror will go undetected even after scrubbing.
For system administrations this behavior is non-intuitive and in
a worst case scenario could result in the only good copy of the
data being unknowingly detached from the mirror.
This change resolves the issue by reading all replacing/sparing
mirror children when scrubbing. When the BP isn't available for
verification, then compare the data buffers from each child. They
must all be identical, if not there's silent damage and an error
is returned to prompt the top-level vdev to issue a repair I/O to
rewrite the data on all of the mirror children. Since we can't
tell which child was wrong a checksum error is logged against the
replacing or sparing mirror vdev.

Page writebacks with WB_SYNC_NONE can take several seconds to complete
since they wait for the transaction group to close before being
committed. This is usually not a problem since the caller does not
need to wait. However, if we're simultaneously doing a writeback
with WB_SYNC_ALL (e.g via msync), the latter can block for several
seconds (up to zfs_txg_timeout) due to the active WB_SYNC_NONE
writeback since it needs to wait for the transaction to complete
and the PG_writeback bit to be cleared.
This commit deals with 2 cases:
- No page writeback is active. A WB_SYNC_ALL page writeback starts
and even completes. But when it's about to check if the PG_writeback
bit has been cleared, another writeback with WB_SYNC_NONE starts.
The sync page writeback ends up waiting for the non-sync page
writeback to complete.
- A page writeback with WB_SYNC_NONE is already active when a
WB_SYNC_ALL writeback starts. The WB_SYNC_ALL writeback ends up
waiting for the WB_SYNC_NONE writeback.
The fix works by carefully keeping track of active sync/non-sync
writebacks and committing when beneficial.

This behavior is expected and correct, but results in a

failed when the MOS blocks have clearly been overwritten.
When testing failures were rare enough that a single retry
