filetest_001_pos consumes the output using read -r, assigning each
field to a variable. The problem comes when a vdev is marked degraded,
which appends extra fields to the line. This causes the trailing text
to be treated as part of the `cksum` variable. Using awk instead of
read -r allows us to extract the checksum error count from the output
whether the vdev is degraded or not.

PR #8114 quoted the ${ENCRYPTIONROOT} parameter to ensure we don't
lose spaces when unlocking root filesystem in the off chance that
it has a space in its name.
Unfortunately, dracut and initramfs-tools do not actually get the
quotes from the cmdline. If we use root=ZFS="root pool/filesystem
name" the script still only sees root=ZFS=root and no quotation
marks.
Because + is a reserved character in ZFS, it's used as a
placeholder for spaces in the kernel cmdline. In this way,
root=ZFS=root+pool/filesystem+name will properly expand by
replacing the character with sed (POSIX compliant method).

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.

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.

It's helpful if there are pools with same names,
but you need to use only one of them.
Main case is twin servers, meanwhile some software
requires the same name of pools (e.g. Proxmox).

e2fsprogs v1.44.1, which provides lsattr, added a new attribute
for ext3 called "verity". It is reported after the project quota
flag as a 'V' character in the `lsattr` output.
Update projectid_001_pos.ksh and projecttree_001_pos.ksh to use
a pattern which will match the expected output in both cases.
