23a1916935 nvme: add function to get the max zone append data transfer size
The zone append command, which is part of the Zoned Namespace Command Set,
has a maximum data transfer size that can be less than or equal to mdts.

Since zone append commands will not be allowed to be split, the user has
to be able to get the maximum zone append data transfer size. Add a
function that returns this limit.

be3ff9c0b5 nvme: add function to get ZNS num zones
Add a function to get the number of zones for a zoned namespace.

Since the ZNS specification does not allow zone size == 0,
divide by zero should not be possible on a spec compliant drive.

d8f4bbeb43 lib/nvme: Add spdk_nvme_detach_async() and spdk_nvme_detach_poll_async()
Add two new public APIs, spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() to detach multiple controllers in parallel
as a simple manner to users.

Hold the target controller to nvme_ctrlr_detach_ctx because users
will free any object which held it after returning spdk_nvme_detach_async().

spdk_nvme_detach_ctx holds all nvme_ctrlr_detach_ctx in a sequence
by linked list.

spdk_nvme_detach_ctx has a boolean variable polling_started to prevent
the user from calling spdk_nvme_detach_async() while
spdk_nvme_detach_poll_async() is called repeatedly.

3be2935701 nvme: move ZNS specific functions to their own header file
Move ZNS specific functions to their own header file:
include/spdk/nvme_zns.h.
This is similar to how it's done for e.g. NVMe-oF with
include/spdk/nvmf.h.

This avoids cluttering the nvme.h header with ZNS specific functions.

A SPDK program that wants to use the spdk_nvme_zns_* functions will
need to include include/spdk/nvme_zns.h, however, this is similar
to how e.g. spdk_nvmf namespaced functions work.
This change is safe to do now, since there is no SPDK release with
ZNS so far.

4e06de69b8 nvme: expose functions to manage queue identifiers
In cases where the SPDK nvme driver is being used as a validation/test
vehicle, users may need to allocate a currently unused qid that can be
used for creating queues using the raw interfaces. One example would be
testing N:1 SQ:CQ mappings which are supported by PCIe controllers but
not through the standard SPDK nvme driver APIs.

These new functions fulfill this purpose, and ensure that the allocated
qid will not be used by the SPDK driver for any future queues allocated
through the spdk_nvme_ctrlr_alloc_io_qpair API.

71da42e953 lib/nvme: Add spdk_nvme_ctrlr_cmd_abort_ext() to abort commands whose cb_arg matches
A new API spdk_nvme_ctrlr_cmd_abort_ext() gets cmd_cb_arg as a
parameter, and use it to abort requests whose cb_arg matches cmd_cb_arg.

The caller can set the parameter qpair to NULL if it wants to abort
requests on admin qpair.

Hold ctrlr->ctrlr_lock throughout because abort request is submitted
to admin qpair.

The API is not critical for performance, and so initialize parent
data first.

The API is for a specific qpair, and so hold SQID in the parent,
and it is copied to the children. On the other hand, CID is set
to child when request to abort is found.

Use an new helper function nvme_transport_qpair_iterate_requests()
to add abort request for each outstanding request which has
cmd_cb_arg as its callback context.

The case is possible such that the request to abort is not outstanding
yet but queued. Hence abort queued requests which has cmd_cb_arg
as its callback context too, but it is done only if there is no error
so far.

If only queued requests are aborted and there is no outstanding
request to abort, complete with success synchronously.

If there is no outstanding or queued request to abort, return -ENOENT.

When any abort request is submitted, the difference between success
and failure is only bit 0 of CDW0 according to the NVMe specification.

We cannot the existing helper functions nvme_request_add_child() and
nvme_cb_complete_child() but can use nvme_request_remove_child().
nvme_qpair_submit_request() may use only nvme_request_remove_child()
from these three helper functions. Hence we use req->parent as other
types of request do.
