In multi-process, we need to make sure we don't
complete a register_operation in the wrong process. So
save the pid in the nvme_register_completion structure

Almost all of these files share the exact same license text,

nvme_qpair_abort_queued_reqs() is used to abort queued requests that

This change is required for the NVMe bdev module to be resilient for I/O

SC is set to SC_INTERNAL_DEVICE_ERROR if a request is failed to submit

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.

When we disconnect a qpair, part of the code path is
calling _nvme_qpair_abort_queued_reqs. This takes
care of aborting any requests that were queued waiting
for slots to open on the submission queue.
It walks the STAILQ one by one and manually completes
them with ABORT status back to the caller.
But if the callback path submits another request, this
request may also get queued to the end of the queued_req
TAILQ. This can result in an infinite loop.
The solution is to use an STAILQ_SWAP to a local, empty
STAILQ. Then we ensure we only abort the requests that
were queued when _nvme_qpair_abort_queued_reqs() started
executing.
Fixes issue #1588.
I used the multipath.sh test to reproduce this on my local
system. If it ever dropped into the STAILQ loop in this
function, we would hit the infinite loop. With this patch,
I confirmed locally that now we safely avoid the infinite
loop and the test passes.

Use another list dedicated to hold queued requests being aborted
to avoid potential infinite recursive calls.
Add a helper function nvme_qpair_abort_queued_req() to move requests
whose cb_arg matches from qpair->queued_req to qpair->aborted_queued_req.
Then nvme_qpair_resubmit_requests() aborts all requests in
qpair->aborted_queued_req.
The first idea was that nvme_qpair_abort_queued_req() aborts queued
requests directly. However, this caused infinite recursive calls.
Hence separate requesting abort to queued requests and actually
aborting queued requests.
The detail of the infinite recursive calls is as follows:
Some SPDK tool submits the next request from the callback to the completion
of a request in the completion polling loop. For such tool, if the callback
submits a request and then aborts the request immediately, and the request
could not be submitted but queued, it will create infinite recursive calls
by request submit and abort, and it will not be able to get out of
completion polling loop.

When a NVMe device is hot removed, subsequent calls to
nvme_qpair_submit_request can fail with ENXIO.
The failure path handling for ENXIO did not free the request which
exhausts the qpair's free_req list eventually and all IOs are stuck
going forward.
This fix adds the same cleanup handling to nvme_qpair_submit_request
for this error case as it is done in _nvme_qpair_submit_request.

already submitted, the function can return success to wait for those children
to complete, but the parent should be set to failure.

By aborting all requests from every qpair when it is disconnected,
we can completely avoid having to abort requests when we enable the
qpair since nothing will be left enabled.

When we destroy a qpair, we need to flush all of the I/O.
But some applications will try to resubmit that I/O. We need
to not re-queue those I/O while in the context of the destroy
call so as to avoid an infinite loop.
