The config lock must be held for the duration of the MMP write.
Since the I/Os are executed via map_nowait(), the done function
is the only place where we know the write has completed.
Since SCL_STATE is taken as reader, overlapping I/Os do not
create a deadlock. The refcount is simply increased when new
I/Os are queued and decreased when I/Os complete.
Test case added which exercises the probe IO call path to
verify the fix and prevent a regression.

Therefore, increasing the delay should ensure the zed has

When an IO fails then zio_vdev_io_done() can call vdev_probe()
to determine the health of the vdev. This is safe as long as
the original zio was submitted with zio_wait() and holds the
SCL_STATE_ALL lock over the operation.
If zio_no_wait() was used then the done callback will submit
the probe IO outside the SCL_STATE_ALL lock and hit this
ASSERT in zio_create()
ASSERT(!vd || spa_config_held(spa, SCL_STATE_ALL, RW_READER));
Resolve the issue by only allowing vdev_probe() to be called
when there's a waiter indicating the caller is using zio_wait().
This assumes that caller is still holding SCL_STATE_ALL.
This issue isn't MMP specific but was surfaced when testing.
Without this patch it can be reproduced by running:

Add multihost=on|off pool property to control MMP. When enabled
a new thread writes uberblocks to the last slot in each label, at a
set frequency, to indicate to other hosts the pool is actively imported.
These uberblocks are the last synced uberblock with an updated
timestamp. Property defaults to off.
During tryimport, find the "best" uberblock (newest txg and timestamp)
repeatedly, checking for change in the found uberblock. Include the
results of the activity test in the config returned by tryimport.
These results are reported to user in "zpool import".
Allow the user to control the period between MMP writes, and the
duration of the activity test on import, via a new module parameter
zfs_multihost_interval. The period is specified in milliseconds. The
activity test duration is calculated from this value, and from the
mmp_delay in the "best" uberblock found initially.

If no spl_hostid was set, and no /etc/hostid file existed, the user
and kernel would have different values for the hostid.
The kernel's would be 0. User space's would depend on the libc
implementation. On systems with glibc, it would be a generated value,
probably the first 4 bytes of an IP address (see man 3 gethostid and
comments above hostid_read in SPL for details).
This then causes the hostid stored in the labels and in the pool
config not to match the hostid userspace obtains from
get_system_hostid().
Since the kernel has no way to know the libc's generated hostid value,
it serves no purpose for ZFS to use the value.
This patch changes user space's get_system_hostid() to conform to the
kernel's method, first checking for the spl_hostid via sysfs, and then
reading from /etc/hostid directly.
It does not look up spl_hostid_path, because if that is set and the
file it pointed to exists, spl_hostid will reflect its contents.
It eliminates the call to libc's gethostid().

The problem is that zfs_get_data() supplies a stale zgd_bp to

zfs_get_data() doesn't hold any DMU-related locks, so after it
copies db_blkptr to zgd_bp, dbuf_write_ready() could change
db_blkptr, and dbuf_write_done() could remove the dirty record.
dmu_sync() then sees the stale BP and that the dbuf it not dirty,
so it is eligible for nop-writing.
The fix is for dmu_sync() to copy db_blkptr to zgd_bp after
acquiring the db_mtx. We could still see a stale db_blkptr,
but if it is stale then the dirty record will still exist and
thus we won't attempt to nopwrite.

The existing kernel-side code only provides a method to rollback to a
latest snapshot, whatever it happens to be at the time when the rollback
is actually done. That could be unsafe or confusing in environments
where concurrent DSL changes are possible as the resulting state could
correspond to a newer or older snapshot than the originally requested
one.
This change allows to amend that method such that the rollback is
performed only when the latest snapshot has a specific name. That is,
if a new snapshot is concurrently created or the target snapshot is
destroyed, then no rollback is done and EXDEV error is returned.
New libzfs_core function lzc_rollback_to() is provided for the new
functionality. libzfs is changed to use lzc_rollback_to() to implement
zfs rollback command.
Perhaps we should return different errors to distinguish the case where
the desired snapshot exists but it's not the latest snapshot and the
case where the desired snapshot does not exist.

dir_is_empty_readdir() immediately returns if fdopendir() fails.
We should close dirfd when that happens.

The problem is that when dsl_bookmark_destroy_check() is
executed from open context (the pre-check), it fills in
dbda_success based on the existence of the bookmark. But
the bookmark (or containing filesystem as in this case)
can be destroyed before we get to syncing context. When
we re-run dsl_bookmark_destroy_check() in syncing context,
it will not add the deleted bookmark to dbda_success,
intending for dsl_bookmark_destroy_sync() to not process
it. But because the bookmark is still in dbda_success from
the open-context call, we do try to destroy it.
The fix is that dsl_bookmark_destroy_check() should not
modify dbda_success when called from open context.
