The "clone" bio may be processed and freed before the check
"clone->bi_status == BLK_STS_IOERR" - so this check can access invalid
memory.

proper fix has been made to the block loopback driver.

- Fix DM kcopyd to wakeup so failed subjobs get completed.

small tweaks (SPDX license identifiers and fix typos).

- Fix DM integrity range locking race by tracking whether journal has
changed.

- Fix DM dust target to detect reads of badblocks beyond the first 512b
sector (applicable if blocksize is larger than 512b).

- Fix DM persistent-data issue in both the DM btree and DM
space-map-metadata interfaces.

- Fix out of bounds memory access with certain DM table configurations.

dm zoned: properly handle backing device failure

dm-zoned is observed to lock up or livelock in case of hardware
failure or some misconfiguration of the backing zoned device.

This patch adds a new dm-zoned target function that checks the status of
the backing device. If the request queue of the backing device is found
to be in dying state or the SCSI backing device enters offline state,
the health check code sets a dm-zoned target flag prompting all further
incoming I/O to be rejected. In order to detect backing device failures
timely, this new function is called in the request mapping path, at the
beginning of every reclaim run and before performing any metadata I/O.

The proper way out of this situation is to do

dmsetup remove <dm-zoned target>

and recreate the target when the problem with the backing device
is resolved.

dm zoned: improve error handling in i/o map code

Some errors are ignored in the I/O path during queueing chunks
for processing by chunk works. Since at least these errors are
transient in nature, it should be possible to retry the failed
incoming commands.

The fix -

Errors that can happen while queueing chunks are carried upwards
to the main mapping function and it now returns DM_MAPIO_REQUEUE
for any incoming requests that can not be properly queued.

Error logging/debug messages are added where needed.
