along with the "regular" io_uring, libaio, POSIX aio, emulated aio (via threadpools) etc.
Code changes done :
a. Addition of xNVMe submodule to SPDK
b. Modification of RPC scripts to Create / Delete xNVMe BDEVs
c. Implementation of xNVMe BDEV module

nvme_ctrlr_init_ana_log_page() had used cdata->mnan as active ns count
to allocate a buffer and read a ANA log page into the buffer.
However, cdata->mnan was larger than the real active ns count and caused
an issue when the corresponding NVMe-oF target set the bit 18 of the SGL
support field in the Identify Controller Data structure.
We still need to use cdata->mnan to allocate the buffer because
number of namespaces may be increased dynamically after initialization.
Hence, rename nvme_ctrlr::ana_log_page_size to
nvme_ctrlr::max_ana_log_page_size and calculate and use the active ns
count to read the ANA log page. Check if the current ana_log_page_size
is not larger than nvme_ctrlr->max_ana_log_page_size.

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:
1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

Calculation of the ANA log page size should use the
identify ctrl MNAN field
(maximum number of allowed namespaces)
not the NN (maximum valid nsid value).
An ANA-enabled controller must have a non-zero MNAN value,
see NVMe Base Specification, Figure 251,
therefore nvme_ctrlr_init_ana_log_page() may safely use MNAN.
Since NN might be much higher than MNAN,
ANA log size based on NN may results in a very large
log page and cause a failure to get ANA log,
e.g. if it is larger than the controller's MDTS.
Fix: replace cdata->nn with cdata->mnan
in nvme_ctrlr_init_ana_log_page()

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

after the hardware has actually been stopped.

Replaced the TODO comment with an error handing in case SPDK fails to

will use the bdev's no memory retry mechanism to handle the failure.

The following patches will swap the ordering of destroying I/O qpairs
and disconnecting a controller for PCIe transport to fix a github issue.
Setting callback and calling spdk_nvme_ctrlr_disconnect() have been
executed in two cases now.
After the following patches, these will be executed in three cases.
Factoring out these into a helper function will be rewarded.

The NVMe bdev module supported active-passive policy for multipath mode
first. By this patch, the NVMe bdev module supports active-active policy
for multipath node next. Following the Linux kernel native NVMe multipath,
the NVMe bdev module supports round robin algorithm for active-active
policy.
The multipath policy, active-passive or active-active, is managed per
nvme_bdev. The multipath policy is copied to all corresponding
nvme_bdev_channels.
Different from active-passive, active-active caches even non_optimized
path to provide load balance across multiple paths.

If we specify a preferred path manually for each NVMe bdev, we will
be able to realize a simple static load balancing and make the failover
more controllable in the multipath mode.
The idea is to move I/O path to the NVMe-oF controller to the head of
the list and then clear the I/O path cache for each NVMe bdev channel.
We can set the I/O path to the I/O path cache directly but it must be
conditional and make the code very complex. Hence, let find_io_path() do
that.
However, a NVMe bdev channel may be acquired after setting the preferred
path. To cover such case, sort the nvme_ns list of the NVMe bdev too.
This feature supports only multipath mode. The NVMe bdev module supports
failover mode too. However, to support the latter, the new RPC needs to
have trid as parameters and the code and the usage will be come very
complex. Add a note for such limitation.
To verify one by one exactly, add unit test.

ACWU and NACWU are 0-based values. But spdk_bdev_get_acwu()
specifies the compare-and-write-unit in terms of blocks

When sending a fused compare and write command, we pass a callback
bdev_nvme_comparev_and_writev_done that we expect to be called twice
before marking the io as completed. In order to detect if a call to
bdev_nvme_comparev_and_writev_done is the first or the second one, we
currently rely on the opcode in cdw0. However, cdw0 may be set to 0,
especially when aborting the command. This may cause use-after-free
issues and this may call the user callbacks twice instead of once.
Use a bit in the nvme_bdev_io instead to keep track of the number of
calls to bdev_nvme_comparev_and_writev_done.

Add an new RPC bdev_nvme_get_io_paths to query all active I/O paths.
One io_path belongs to One nvme_bdev_channel.
Each nvme_bdev_channel is associated with one nvme_bdev.
If the RPC bdev_nvme_get_io_paths has a bdev name as a parameter
it can use spdk_for_each_channel() simply for the corresponding
nvme_bdev.
However, users will want to know I/O paths of all nvme_bdevs like
the RPC bdev_get_bdevs.
One io_path has one nvme_qpair. One nvme_qpair belongs to one
nvme_poll_group. By relying on these relationships, the RPC
bdev_nvme_get_io_paths traverses all nvme_poll_groups by using
spdk_for_each_channel() to g_bdev_nvme_ctrlrs.
The RPC bdev_nvme_get_io_paths has two modes, display all or
the specified NVMe bdev's active I/O paths.
The specified bdev name is used just for comparison and empty
array is returned if no matched io_path is found.

Previously, if a namespace is in ANA inaccessible state, I/O had been
queued infinitely. Fix this issue according to the NVMe spec.
Add a temporary poller anatt_timer and a flag ana_transition_timedout for
each nvme_ns.
Start anatt_timer if the nvme_ns enters ANA transition. If anatt_timer
is expired, set ana_transition_timedout to true. Cancel anatt_timer or
clear ana_transition_timedout if the nvme_ns exits ANA transition.
nvme_io_path_become_available() returns false if ana_transition_timedout
is true.
