It's possible for a vdev to be flagged for async remove after the pool
has suspended. If the removed device has been returned when the pool is
resumed, the ASYNC_REMOVE task will still run at the end of txg, and
remove the device from the pool again.
To fix, we clear the async remove flag at reopen, just as we did for the
async fault flag in 5de3ac223.

zfs_arc_shrinker_limit was introduced to avoid ARC collapse due to
aggressive kernel reclaim. While useful, the current default (10000) is
too prone to OOM especially when MGLRU-enabled kernels with default
min_ttl_ms are used. Even when no OOM happens, it often causes too much
swap usage.
This patch sets zfs_arc_shrinker_limit=0 to not ignore kernel reclaim
requests. ARC now plays better with both kernel shrinker and pagecache
but, should ARC collapse happen again, MGLRU behavior can be tuned or
even disabled.
Anyway, zfs should not cause OOM when ARC can be released.

In Linux, block devices currently lack support for `copy_file_range`
API because the kernel does not provide the necessary functionality.
However, there is an ongoing upstream effort to address this
limitation: https://patchwork.kernel.org/project/dm-devel/cover/20240520102033.9361-1-nj.shetty@samsung.com/.
We have adopted this upstream kernel patch into the TrueNAS kernel and
made some additional modifications to enable block cloning specifically
for the zvol block device. This patch implements the platform-
independent portions of these changes for inclusion in OpenZFS.
This patch does not introduce any new functionality directly into
OpenZFS. The `TX_CLONE_RANGE` replay capability is only relevant when
zvols are migrated to non-TrueNAS systems that support Clone Range
replay in the ZIL.

When replacing a disk, a child process is forked to run a script called

code.
However, the _reap_children thread (created from zed_exec_process to
manage zedlets) also waits for all children with the same PGID and can
stole the signal, causing the replace operation to be aborted.
As waitpid returns -1, the parent incorrectly assume that the child
process had an error or was killed. This, in turn, leaves the newly
added disk in REMOVED or UNAVAIL status rather than completing the
replace process.
This patch changes the PGID of the child process execuing the
