This patch is to add the core control policy for the
bandwidth rate limit (max bytes per second). Change
the existing functions for a common name and specially
handle the case when IOPS and bandwidth rate limiting
are both enabled.

To support the bandwidth rate limiting besides the IOPS rate
limiting, this patch is to add the support of the configuration
parse. The format will be as following to have a 10 (10M)

This one is actually a bit tough to deduce in the specification.
The NVMe-oF spec says that QID errors detected in the RDMA
transport shall return an RDMA-specific error indicating
the problem. However, our code doesn't detect the error in
RDMA-specific code, and it isn't clear if the language is
a "must" or a "should".
The NVMe specification does clearly indicate what error
to return on invalid QID in response to a Create
I/O Queue Pair command. For now, return that while
we game plan whether we need to call into the RDMA
transport to correctly report this error.

spck_scsi_task_free_data() is only used in spdk_scsi_task_put().
The latter was called in UT code but this can be removed without any
degradation.
SPDK SCSI layer is relatively matured and these will not be used
out of lib/scsi/task.c.
Additionally memory leak detected by ASAN is fixed in this patch.

Rather than storing nvme_payload::type explicitly, use the SGL reset
function pointer as an indicator: if reset_sgl_fn is non-NULL, then the
payload is an SGL type; otherwise it is a contiguous buffer type.
This eliminates the one-byte type member from struct nvme_payload,
making it an even 32 bytes instead of 33, allowing the removal of the
awkward packing inside struct nvme_request.

of one bdev if another bdev of the same module (nvme, split, etc)
is entirely saturated. This is not the behavior we want,
as these bdevs may not have anything in common.
This `issue` has been fixed just now, but to prevent
it coming back again lets add a unit test for it.
This test case creates two bdevs using two separate
io_devices and checks if ENOMEM handling is somehow common
for these two. It must not be.

The Active NS List code was previously depending on the VER field of the

This commit provides an API to obtain an information about
snapshot and clone relations.
The main objective is:
1) Determinate if we can delete snapshot (if have some created
clones),
2) Provide an information about parent/children nodes to the upper
layer (e.g. lvol)
Realization:
1) Structure parent-children is stored in the blob store object
and updated on:
a) blob store load,
b) blob create/delete,
2) Full information about parent-children is provided via new API:
spdk_blob_get_parent() and spdk_blob_get_children(),
Note:
While we don't store an information about these relations in the
blob store, we need to open all blobs on blob store load to create
it. It should be considered that it have an impact on the blobstore
loading performance.

When testing whether QoS is enabled, the code previously
checked mutable values in the bdev itself. Instead, it needs
to check the flag in the channel.
Right now, QoS can only be configured statically when the
bdev is created. This means that no channels will exist
prior to QoS being turned on, which simplifies setting
the per-channel flag (only need to set it when a channel
is created).

Instead of silently truncating overly-long SCSI dev names, add an

Since we now calculate the length of name up front, this also allows
simplification of the copy into dev->name.
This also ensures that dev->name will always be zero-terminated, so we
can simplify the strnlen() in spdk_bdev_scsi_pad_scsi_name() to a
strlen() and remove the invalid unit test case for padding names longer
than SPDK_SCSI_DEV_MAX_NAME.

As there is no I/O channel associated with the QoS
bdev channel, add the specific functions to handle
the reset operation on the QoS bdev channel. The
reset operation will be conducted on the QoS thread.
Related UT code on QoS with reset operation was also
included.

Users can use RPC to add/remove a namespace to/from
existing NVMe controller, SPDK NVMeoF target will
generate an asynchronous event as an indication to
host when asynchronous event request is available.
While here, we also set the event with invalid log
identifier, so that the host doesn't need to clear
the event. Users can use Set Feature to disable
such event.

Similar with exist vhost scsi/blk target, this commit introduces
a new target: vhost nvme I/O slave target, QEMU will present an
emulated NVMe controller to VM, the SPDK I/O slave target will
process the I/Os sent from Guest VM.
Users can follow the example configuation file to evaluate this
feature, refer to etc/spdk/vhost.conf.in [VhostNvme].

SPKD base bdev might be part of multiple vbdevs. The same is true in
reverse direction. So consider folowing scenario:
bdev3 bdev4 bdev5
| | |
+-+--+ + +--+--+
/ \ | / \
bdev0 bdev1 bdev2
In current implementation bdev0/1/2 will apear as base base for
bdev3/4/5 which is obviously wrong.
This patch try to address this issue.

Blobstore supports only block lengths that are less than
SPDK_BS_PAGE_SIZE or when multiplication of block len
results in SPDK_BS_PAGE_SIZE.
This was checked only on spdk_bs_init(), but not spdk_bs_load().
When not checked, it caused issues with lvol store tasting.
During tasting, there is an attempt to perform spdk_bs_load()
on a given device.
It was possible to hit asserts in blobstore by creating
malloc with block size 8192.
