It is caused by this commit:
4163626c5c
nvmf_tgt_delete_subsystem registers the poller
with function subsystem_delete_event.
subsystem_delete_event is called asynchronously,
the deletion should happen in this function.
Otherwise, with the current code,
g_subsystems_shutdown = true
TAILQ_EMPTY(&g_subsystems) = true
when subsystem_delete_event is firstly called.
If there are multiple subsystems, the logic is wrong.
Thus other subsystem will never be delete. since
we already execute shutdown_complete().
Also add related test scripts.

For namespaces with end-to-end protection information, metadata size
of exactly 8 bytes, and extended LBA configured, the NVMe driver would
calculate the size of the data block incorrectly. The NVMe spec has a
special provision for this specific case (8-byte metadata only) and
PRACT = 1 that requires that the host does not send the metadata as part
of the host memory buffer.
To fix this, clean up the calculation of the per-block data transfer
size by adding a new extended_lba_size field in the namespace, which
represents the total size of data to be transferred per block based on
the namespace's configured metadata size and whether it transfers
metadata as part of the data buffer. Then add the special case for
PRACT = 1 and PI configured and extended LBA in the R/W helper
functions.

Convert the number parsing function into a linear sequence with a goto
label for each state, rather than a single loop with a state variable.
This makes the code easier to read and also improves speed (better
branch prediction and smaller inner loops for the common case).
On my test system, jsoncat citylots.json > /dev/null improves from
~1.7s to ~1.2s.
This changes behavior of some number parsing test cases: inputs matching
the number grammar as defined by JSON will be returned even if there is
trailing garbage, consistent with the rest of the parser. For example,
the input 01 will be parsed as a valid number 0 followed by trailing 1.
This only makes any difference when the full input is a single
number value, since if the value was nested in an object or array, the
trailing garbage will not match the expected syntax and the whole parse
will fail with SPDK_JSON_PARSE_INVALID (e.g. [00 will parse the first 0
as a number and then fail on the second 0, since only a comma or right
square bracket would be accepted).

An old prototype SPDK AHCI driver would return
TASK_SET_FULL if all NCQ slots were full on a given
disk. This would kick the SCSI task back to the LUN
to be retried later. Since then, we have pushed
responsibility onto the bdev modules themselves
to handle this kind of queueing/retry logic.
Removing this logic allows us to make some additional
changes that enable tasks to get completed inline without
an extra event callback to handle completion. We also
no longer need to worry about checking if pending tasks
need to be executed in the complete_task() routine, since
the execute() routine will now always exhaust the pending_task
list.

remove the list when got ACK from initiator, but for this part of
logic, the reference count of primary task was not released correctly.

Instead of the next_sge callback returning the physical address
directly, make it return the virtual address and convert to physical
address inside the NVMe library.
This is necessary for NVMe over Fabrics host support, since the RDMA
userspace API requires virtual addresses rather than physical addresses.
It is also more consistent with the normal non-SGL NVMe functions that
already take virtual addresses.

instead.

Since we are usually going to be removing multiple events from the queue
at once, use the DPDK burst dequeue interface to improve efficiency.
Also rework the event queue runner to always process a fixed maximum
number of events per timeslice for simplicity. This removes the
rte_ring_count() call from the hot path and improves fairness between
events and pollers.
Now that events are dequeued in bulk, we can also put the event objects
back into the mempool in bulk. Add an env wrapper around
rte_mempool_put_bulk() and use it to free all of the events at once.
Basic performance benchmark using test/lib/event/event/event -t 10
is improved: previously ~40 million events per second, now ~46 million
events per second.

- Split the part that gets a PCI device's address into its own function,
spdk_pci_device_get_addr(). This is useful outside of the comparison
function and is orthogonal to comparing addresses.
- Make the comparison function take two addresses instead of a device
and an address. The more general form will be useful with addresses
that are not directly associated with a device. Because of this, also
rename the function from spdk_pci_device_compare_addr() to
spdk_pci_addr_compare().
- Return a signed value similar to strcmp() so that addresses can be
ordered, not just compared for equality.
