In order to validate the gang block code ztest is configured to
artificially force a fraction of large blocks to be written as
gang blocks. The default setting chosen for this was to
write 25% of all blocks 32k or larger using gang blocks.
The confluence of an unrealistically large number of gang blocks,
the aggressive fault injection done by ztest, and the split
segment reconstruction logic introduced by device removal has
resulted in the following type of failure:
zdb -bccsv -G -d ... exit code 3
Specifically, zdb was unable to open the pool because it was
unable to reconstruct a damaged block. Manual investigation
of multiple failures clearly showed that the block could be
reconstructed. However, due to the large number of damaged
segments (>35) it could not be done in the allotted time.
Furthermore, the large number of gang blocks was determined
to be the reason for the unrealistically large number of
damaged segments. In order to make this situation less
likely, this change both increases the forced gang block
size to 64k and reduces the frequency to 3% of blocks.

When we delete a snapshot, we consolidate some bpobj's together because
we no longer need to keep their entries in separate buckets. This is
done in constant time by including the "sub" bpobj by reference in the
parent bpobj.
After many snapshots have been deleted, we may have many sub-bpobj's.
Usually, most sub-bpobj's don't contain many BP's. Compared to this
small payload, the sub-bpobj is relatively heavyweight since it is a
object in the MOS. A common scenario on a long-lived pool is for the
vast majority of MOS objects to be small sub-bpobj's.
To improve this situation, when consolidating bpobj's together,
bpobj_enqueue_subobj() can copy the contents of small bpobj's into the
parent, and then delete the enqueued bpobj, rather than including it by
reference. Since this copying is limited in size (to one block), the
consolidation is still constant time, though with a larger constant due
to reading in the one block of the enqueued bpobj.
This idea and mechanism are similar to how we handle "sub-subobj's".
When including a sub-bpobj by reference, if the sub-bpobj itself has
less than a block of sub-sub-bpobj's, the list of sub-sub-bpobj's is
copied to the parent bpobj's list of sub-bpobj's.

1) A new disk, in the same physical location, is automatically

2) It completes the replacement process, and
3) The pool is now ONLINE and healthy.
There is no need to remove the scsi_debug module. After exporting

This patch resolves a problem where the -G option in both zdb and
ztest would cause the code to call __dprintf() to print zfs_dbgmsg
output. This function was not properly wired to add messages to the
dbgmsg log as it is in userspace and so the messages were simply
dropped. This patch also tries to add some degree of distinction to
dprintf() (which now prints directly to stdout) and zfs_dbgmsg()
(which adds messages to an internal list that can be dumped with
zfs_dbgmsg_print()).
In addition, this patch corrects an issue where ztest used a global
variable to decide whether to dump the dbgmsg buffer on a crash.
This did not work because ztest spins up more instances of itself
using execv(), which did not copy the global variable to the new
process. The option has been moved to the ztest_shared_opts_t
which already exists for interprocess communication.
This patch also changes zfs_dbgmsg_print() to use write() calls
instead of printf() so that it will not fail when used in a signal
handler.

Currently, if a resilver is triggered for any reason while an
existing one is running, zfs will immediately restart the existing
resilver from the beginning to include the new drive. This causes
problems for system administrators when a drive fails while another
is already resilvering. In this case, the optimal thing to do to
reduce risk of data loss is to wait for the current resilver to end
before immediately replacing the second failed drive, which allows
the system to operate with two incomplete drives for the minimum
amount of time.
This patch introduces the resilver_defer feature that essentially
does this for the admin without forcing them to wait and monitor
the resilver manually. The change requires an on-disk feature
since we must mark drives that are part of a deferred resilver in
the vdev config to ensure that we do not assume they are done
resilvering when an existing resilver completes.

The boolean featureflags in use thus far in ZFS are extremely useful,
but because they take advantage of the zap layer, more interesting data
than just a true/false value can be stored in a featureflag. In redacted

a redacted dataset.
This change adds the ability for ZFS to store types other than a boolean
in a featureflag. The only other implemented type is a uint64_t array.
It also modifies the interfaces around dataset features to accomodate
the new capabilities, and adds a few new functions to increase

only way a zap_lookup() can fail is if the requested entry is
missing. While this is the most common cause, it's not the only
cause. Attemping to access a damaged ZAP will result in other
errors.
The most likely scenario for accessing a damaged ZAP is during
an extreme rewind pool import. Under these conditions the pool
is expected to contain damaged objects and the import code was
updated to handle this gracefully. Getting an ECKSUM error from
these ZAPs after the pool in import a far less likely, therefore
the behavior for call paths was not modified.

The ZFS range locking code in zfs_rlock.c/h depends on ZPL-specific
data structures, specifically znode_t. However, it's also used by
the ZVOL code, which uses a "dummy" znode_t to pass to the range
locking code.
We should clean this up so that the range locking code is generic
and can be used equally by ZPL and ZVOL, and also can be used by
future consumers that may need to run in userland (libzpool) as
well as the kernel.
Porting notes:
* Added missing sys/avl.h include to sys/zfs_rlock.h.
* Removed 'dbuf is within the locked range' ASSERTs from dmu_sync().
This was needed because ztest does not yet use a locked_range_t.
* Removed "Approved by:" tag requirement from OpenZFS commit
check to prevent needless warnings when integrating changes
which has not been merged to illumos.
* Reverted free_list range lock changes which were originally
needed to defer the cv_destroy() which was called immediately
after cv_broadcast(). With d2733258 this should be safe but
if not we may need to reintroduce this logic.
* Reverts: The following two commits were reverted and squashed in
to this change in order to make it easier to apply OpenZFS 9689.
- d88895a0, which removed the dummy znode from zvol_state
- e3a07cd0, which updated ztest to use range locks
* Preserved optimized rangelock comparison function. Preserved the
rangelock free list. The cv_destroy() function will block waiting
for all processes in cv_wait() to be scheduled and drop their
reference. This is done to ensure it's safe to free the condition
variable. However, blocking while holding the rl->rl_lock mutex
can result in a deadlock on Linux. A free list is introduced to
defer the cv_destroy() and kmem_free() until after the mutex is
released.

Historically, zpool status prints "(repairing)" for any drives that
have errors during a scrub:
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
/tmp/file1 ONLINE 13 0 0 (repairing)
/tmp/file2 ONLINE 0 0 0
/tmp/file3 ONLINE 0 0 0
This was accidentally broken in "OpenZFS 9166 - zfs storage pool
checkpoint" (d2734cc). This patch adds it back in.

for receive-related changes in header files.
