A number of modules (RAID, logical volumes) have logical
"stripes" that require splitting an I/O into several
child I/O. For example, on a RAID-0 with 128KB strip size,
an I/O that spans a 128KB boundary will require sending
one I/O for the portion that comes before the boundary to
one member disk, and another I/O for the portion that comes
after the boundary to another member disk. Logical volumes
are similar - data is allocated in clusters, so an I/O that
spans a cluster boundary may need to be split since the
clusters may not be contiguous on disk.
Putting the splitting logic in the common bdev layer ensures
bdev module authors don't have to always do this themselves.
This is especially helpful for cases like splitting an I/O
described by many iovs - we can simplify this a lot by
handling it in the common bdev layer.
Note that currently we will only submit one child I/O
at a time. This could be improved later to submit multiple
child I/O in parallel, but the complexity in the iov splitting
code also increases a lot.
Note: Some Intel NVMe SSDs have a similar characteristic.
We will not use this bdev stripe feature for NVMe though -
we want to primarily use the splitting functionality inside
of the NVMe driver itself to ensure it remains fully
functional. Many SPDK users use the NVMe driver without
the bdev layer.

The intents of these arrays was to keep track in the
bdev layer of all base<->virtual bdev relationships -
i.e. which member disk bdevs make up a RAID bdev,
which logical volume bdevs are associated with a
bdev that contains an lvolstore, etc.
Currently none of this is used however. And trying
to keep track in the bdev layer instead of asking
the bdev modules for the relationships has a number
of complications. Early one, we tried to do this
with TAILQs - but that doesn't work since this can't
be done with a single TAILQ_ENTRY in the bdev
structures. So we moved to arrays - that works a bit
better, but then the pointer arrays have to be
realloc'd which isn't ideal.
The biggest problem though with these arrays is that
they held bdev pointers - not bdev descriptor pointers.
It's not really valid to access bdevs without a
descriptor - the descriptors are what make sure active
references are accounted for when a bdev is hotplugged.
Of course the bdev layer knows when a bdev is getting
removed and could go and do the updates to these
arrays separately - but that just seems very convoluted.
So for now just remove these arrays completely. If
there is a future need for the bdev layer to
understand relationships between bdevs, we can add
module APIs so that the generic layer can ask
the modules about the relationships.

When an SPDK application shuts down, the bdev layer will
automatically unregister all of the bdevs to ensure they
are properly quiesced and cleaned up.
Some modules may want to perform different operations when
a bdev is destructed during normal runtime vs. shutdown.
For example, for lvol, when the last lvol is cleaned up,
it should unload the lvolstore, release and close the bdev
that contains the lvolstore. You never want to do this
during normal runtime though - it is perfectly valid to
have an lvolstore that contains no lvols. RAID and future
bdev modules such as multipath have similar use cases.
So add a new bdev module callback named "fini_start".
If a module specifies a function pointer for this callback,
the bdev layer will call it before it starts the bdev
unregistrations.
This enables some future patches to the bdev layer such
that it will always unregister block devices that are not
claimed (i.e. logical volumes) before block devices that
are claimed (i.e. the bdev containing an lvolstore).

If the controller has a serious error and set the Controller
Fatal Status field to 1, host driver does not know this error,
while here, when timeout happens, try to detect the CFS and
reset the controller to recover from such fatal status.

Currently, the bdev layer iterates over all of the
existing channels of a bdev to collect I/O
statistics. But this ignores statistics for
channels that are deleted.
Fix that by keeping an io_stat structure in the
bdev which accumulates statistics for deleted
channels. Use the bdev mutex to protect these
accumulations.

Two extra fields are added to the iostat rpc.
1. io_time. The amount of time since queue depth tracking was
enabled that has been spent on I/O processing.
2. weighted_io_time. Incremented each time this bdev's queue depth is
polled by the amount of time spent processing I/O since the last polling
event times the measured queue depth.

Daisuke Aoyama originally contributed to istgt, the
iSCSI target in FreeBSD. The SPDK iSCSI code is
originally derived from that. Due to copy and paste,
some incorrect copyright attributions have been added
to other files that do not derive from istgt, so
this patch removes those.
It is doubtful, at this point, that there is any code
whatsoever that remains from the original istgt, but
we can revisit that at a later time.

Since destroy_lvol_bdev was implemented, it is now more convinient
to call destroy/unload for lvol store explicitly.
Rather than using lvs struct to pass a request checked on each

This patch fixes lvol delete behaviour.
First, we look if there are any dependencies that disallow lvol deletion.
If there are any (i.e. dependent clones) we fail.
Otherwise we delete lvol and unregister associated bdev.
destroy_bdev no longer deletes lvol.

Change the type of nvme_timeout parameter in
spdk_nvme_ctrlr_register_timeout_callback from uin32_t to uint64_t.
Reason: This will make the timeout trigger test more flexible and
will not affect the original meanings.
Also for the configuration file, still maintain the compatability
support

When hot removal of a LUN is started, callback is called for each
iSCSI connection which accesses the LUN. Callback checks all transfer
tasks complete and then close the LUN.
If the connection clears all transfer tasks before getting all responses
to them from the initiator, the initiator continues to retry data write.
Hence the connection have to wait until all transfer tasks complete.
