The change is simple -- restore the original code so that the VDEV
path is updated when using by-id paths. The more challenging part
was to devise a second ZTS test, that would test auto-replace for
'by-id' and help prevent a future regression.
With that new test, we can now do an A|B test with , and without,
the fix to confirm that auto-replace for by-id paths works. The
existing auto-replace test, functional/fault/auto_replace_001_pos,
will confirm that we didn't break auto-replace for 'by-vdev' paths.
In the original functional/fault/auto_replace_001_pos test, the disk
wipe (using dd) was not effective in removing the partitioning since
the kernel was never informed of the wipe.
Added a call to wipefs(8) so that the kernel is informed and ZED will
re-partition the device.
Added a validation step that the re-partitioning occurred by
confirming that the GPT partition UUID changes.

Previously, if a cachefile is passed to zpool import, the cached config
is mostly offered as-is to ZFS_IOC_POOL_TRYIMPORT->spa_tryimport(), and
the results are taken as the canonical pool config and handed back to
ZFS_IOC_POOL_IMPORT.
In the course of its operation, spa_load() will inspect the pool and
build a new config from what it finds on disk. However, it then
regenerates a new config ready to import, and so rightly sets the hostid
and hostname for the local host in the config it returns.
Because of this, the "require force" checks always decide the pool is
exported and last touched by the local host, even if this is not true,
which is possible in a HA environment when MMP is not enabled. The pool
may be imported on another head, but the import checks still pass here,
so the pool ends up imported on both.
(This doesn't happen when a cachefile isn't used, because the pool
config is discovered in userspace in zpool_find_import(), and that does
find the on-disk hostid and hostname correctly).
Since the systemd zfs-import-cache.service unit uses cachefile imports,
this can lead to a system returning after a crash with a "valid"
cachefile on disk and automatically, quietly, importing a pool that has
already been taken up by a secondary head.
This commit causes the on-disk hostid and hostname to be included in the
ZPOOL_CONFIG_LOAD_INFO item in the returned config, and then changes the
"force" checks for zpool import to use them if present.
This method should give no change in behaviour for old userspace on new
kernels (they won't know to look for the new config items) and for new
userspace on old kernels (the won't find the new config items).

There are some inconsistencies in the handling of mountpoint
property. This commit updates the behavior and makes it
consistent.
If mountpoint property is set when dataset is unmounted, this
would update the mountpoint property. The mountpoint could be
valid or invalid in this case. Setting the mountpoint property
would result in success in this case. Dataset would still be
unmounted here.
On the other hand, if dataset is mounted and mountpoint
property is updated to something invalid where mount cannot be
successful, for example, setting the mountpoint inside a readonly
directory. This would unmount the dataset, set the mountpoint
property to requested value and tries to mount the dataset. The
mount operation returns error and this error is treated as
overall failure of setting the property while the property is
actually set.
To make the behavior consistent in case dataset is mounted or
unmounted, we should try to mount the dataset whenever mountpoint
property is updated. This would result in mounting the datasets
if canmount property is set to on, regardless if the dataset was
previously unmounted.
The failure in mount operation while setting the mountpoint
property should not be treated as failure, since the property is
actually set now to user requested value.

We've observed this test failing intermittently. When it does, the
"same block" check shows that both files have the same content, that is,
the file was cloned.
The only way this could have happened is if the open txg moved between
the dd and clonefile calls. That's possible because although we set
zfs_txg_timeout to be large, that only affects the wait time in the sync
thread at the start of a new txg; it doesn't change anything if its
currently waiting or working.
So here we just force the txgs to move immediately before, which should
get both operations onto the same txg as intented.

`get_same_blocks` is a helper to compare two files and return a list of

cloning tests.
Previously it was incorrectly called `unique_blocks`, which is the
_inverse_ of what it does (an early version did list unique blocks; it
was changed but the name was not). So if nothing else, it should be
called `duplicate_blocks`.
But, keeping the details of a clone operation in your head is actually
quite difficult, without the additional overhead of wondering how the
tools work. So I've renamed it to better describe what it does, added a
usage note, and changed it to return block indexes from 0 instead of 1,
to match how L0 blocks are normally counted.

This implements a binary search algorithm for B-Trees that reduces
branching to the absolute minimum necessary for a binary search
algorithm. It also enables the compiler to inline the comparator to
ensure that the only slowdown when doing binary search is from waiting
for memory accesses. Additionally, it instructs the compiler to unroll
the loop, which gives an additional 40% improve with Clang and 8%
improvement with GCC.
Consumers must opt into using the faster algorithm. At present, only
B-Trees used inside kernel code have been modified to use the faster
algorithm.
Micro-benchmarks suggest that this can improve binary search performance
by up to 3.5 times when compiling with Clang 16 and up to 1.9 times when

For draid vdevs it was possible to initiate both the
sequential and healing resilver at same time.
This fixes the following two scenarios.
1) There's a window where a sequential rebuild can
be started via ZED even if a healing resilver has been
scheduled.
- This is fixed by adding additional check in
spa_vdev_attach() for any scheduled resilver and return
appropriate error code when a resilver is already in
progress.
2) It was possible for zpool clear to start a healing
resilver when it wasn't needed at all. This occurs because
during a vdev_open() the device is presumed to be healthy not
until the device is validated by vdev_validate() and it's set
unavailable. However, by this point an async resilver will
have already been requested if the DTL isn't empty.
- This is fixed by cancelling the SPA_ASYNC_RESILVER
request immediately at the end of vdev_reopen() when a resilver
is unneeded.
Finally, added a testcase in ZTS for verification.
