41bf6280e9 nvme: add num_outstanding_reqs in spdk_nvme_qpair
Added num_outstanding_reqs in struct spdk_nvme_qpair to record outstanding
req number in each qpair. This can be used by multipath to select I/O
path.

Increment num_outstaning_reqs when req is removed from free_req queue and
decrement it when req is put back in free_req queue.

a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

4be6d30438 nvme: Add ctrlr_abort_queued_aborts() into qpair_abort_all_queued_reqs()
nvme_qpair_abort_all_queued_reqs() aborts error injections, queued
requests, aborting queued requests, and outstanding requests. (Aborting
outstanding requests depends on transports.) However, it did not abort
queued aborts.

Include nvme_ctrlr_abort_queued_aborts() into
nvme_qpair_abort_all_queued_reqs() to do really the name of the
function indicates.

nvme_ctrlr_abort_queued_aborts() has been called in a few cases, but
we do not care duplication.

8dd1cd2104 check_format: For C files only, fix return type breaks
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.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
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.

e385cafa72 nvme: Don't log an error when we can't resubmit all requests
In TCP NVME initiator with zero copy enabled requests might be
completed asynchronously - out of qpair_process_completions
context. At the same time we calculate requests completed
asynchronously so that generic NVME layer can resubmit
queued requests after calling qpair_process_requests (or
poll_group_process_requests).
But there is a time gap between async request complete and
qpair_process_completions and the user can submit new IO
thereby decrease the number of free TCP requests. That means
that there might be less free requests than we excpected when
we try to resubmit queued requests.
The solution is change ERRLOG to DEBUG log since it is not a
fatal case.

For the requests which don't have children requests, SPDK may queue them to
the queued_req list due to limited resources, in the completion path, we
may resubmit them to the controller.  When the controller was removed
the submission path will return -ENXIO and we will free the requests directly,
so the callback will not be trigerred for these requests.  Here we added a
flag to indicate the request is from queued_req list or not, so for the failure
submission, we can triger user's callback.

3911922005 nvme: remove redundant transport_qp_is_failed checks
The qpair state transport_qpair_is_failed is actually equivalent to
NVME_QPAIR_IS_CONNECTED in the qpair state machine.

There are a couple of places where we check against
transport_qp_is_failed and then immediately check to see if we are in
the connected state. If we are failed, or we are not in the connected
state we return the same value to the calling function.

Since the checks for transport_qpair_is_failed are not necessary, they
can be removed. As a result, there is no need to keep track of it and it
can be removed from the qpair structure.

13f30a254e nvme: don't disconnect qpairs from admin thread.
Disconnecting qpairs from the admin thread during a reset led to an
inevitable race with the data thread. QP related memory is freed during
the disconnect and cannot be touched from the other threads.

The only way to fix this is to force the qpair disconnect onto the
data thread.

This requires a small change in the way that resets are handled for
pcie. Please see the code in reset.c for that change.

f5d88e46e2 nvme: always set ctrlr->is_failed through API
Use the standard API function to fail the controller in all cases.

This patch, and the several following patches are aimed at creating a
mechanism for reporting up to the application layer that a controller is
failed and or removed. To do this, I use the reset_cb to inform the
upper layer that the controller is failed.
This also requires changes to how we handle a controller reset to
pave the way for doing optional reset retries in the libraries.

e27421b344 nvme: fix req leaks
There are many req leaks when a controller failure
occurs during submitting IO. It must free all of
the children before freeing the parent req.

If a part of the child req has been sent to the back end
and a part of the child req fails, removes the failed req
from the parent req and the parent req must be retained,
freeing the parent req after all of the submitted reqs return.
