83d1bfae41 nvme: Unregister NVMe controller when bdevs creation fails
This patch fixes github issue #385.

a1ec258ac7 Clean up some incorrect Copyright statements
Daisuke Aoyama originally contributed to istgt, the
iSCSI target in FreeBSD. The SPDK iSCSI code is
originally derived from that. Due to copy and paste,
some incorrect copyright attributions have been added
to other files that do  not derive from istgt, so
this patch removes those.

It is doubtful, at this point, that there is any code
whatsoever that remains from the original istgt, but
we can revisit that at a later time.

c3bc40a6ef io_channel: add return value to pollers
This will be used to track time used in pollers - each poller can now
indicate if it found any work to do or not.

For cases where it was obvious and the infrastructure was already in
place, existing pollers have been modified to return 0 or a positive
value to indicate whether work was done.  Other pollers have been
modified to return -1 by default, indicating that the poller isn't
indicating anything about whether work was performed.  This will allow
us to find un-annotated pollers easily in the future and fix them
incrementally.

This patch also remove following macros:
SPDK_GET_BDEV_MODULE - this is not really needed, to find module outside
module translation unit use spdk_bdev_module_list_find()

SPDK_BDEV_MODULE_ASYNC_INIT and SPDK_BDEV_MODULE_ASYNC_FINI - replaced
by bool fields in spdk_bdev_module_if struct.

Instead of requiring each bdev module to track its own bdevs and clean
them up during its fini callback, we can walk the list of registered bdevs
during spdk_bdev_finish() and call spdk_bdev_unregister() on each one of
them before cleaning up the bdev modules.

32bff28a25 nvme: use spdk_pci_device_claim() in nvme_pcie_ctrlr_construct
spdk_pci_device_claim() can be used to ensure only one process
at a time uses any given PCI device.  Previously this was only
used in the bdev_nvme driver - other apps like nvme/perf do
not use spdk_pci_device_claim() and could effectively rip out
the device from a running bdev-based app like the NVMe-oF target.

So instead of modifying all of the nvme apps, put this logic into
the core nvme driver instead so that all applications get the
benefit transparently.  Save the fd when the controller is constructed
and then close it when the controller is destructed to handle the
detach (including hotplug) cases.

simplifies the job of spdk_bdev_initialize() callers providing their own

All callers except the NVMe bdev hotplug poller already used the current
core as the parameter.  The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.

94bc8cfdba bdev: add ENOMEM handling
At very high queue depths, bdev modules may not have enough
internal resources to track all of the incoming I/O.  For example,
we allocate a finite number of nvme_request objects per allocated
queue pair.  Currently if these resources are exhausted, the
bdev module will return failure (with no indication why) which
gets propagated all the way back to the application.

So instead, add SPDK_BDEV_IO_STATUS_NOMEM to allow bdev modules
to indicate this type of failure.  Also add handling for this
status type in the generic bdev layer, involving queuing these
I/O for later retry after other I/O on the failing channel have
completed.

This does place an expectation on the bdev module that these
internal resources are allocated per io_channel.  Otherwise we
cannot guarantee forward progress solely on reception of
completions.  For example, without this guarantee, a bdev
module could theoretically return ENOMEM even if there were
no I/O oustanding for that io_channel.  nvme, aio, rbd,
virtio and null drivers comply with this expectation already.
malloc only complies though when not using copy offload.

This patch will fix malloc w/ copy engine to at least
return ENOMEM when no copy descriptors are available.  If the
condition above occurs, I/O waiting for resources will get
failed as part of a subsequent reset which matches the
behavior it has today.

e36f83d64e bdev_nvme: disable hotplug feature by default
When users don't enable hotplug option in their configuration
section, SPDK will enable it by default. DPDK will print probing
messages continuously for NVMe devices which don't belong to SPDK.

50cbc74a82 bdev/nvme: simplify I/O command block size math
Remove the redundant sector size check; the generic bdev code already
checks for this.

Also use the bdev blocklen field for both offset and size calculations.
The bdev blocklen is the same as the namespace sector size.

60c38d4022 bdev: Change unmap to use offset/len instead of descriptors
This is far simpler, although it does limit the bdev
layer to unmapped just one range per command. In practice,
all of our code reports limits of just one range per command
anyway.

73358c99e1 util/nvme: added io_device unregister callback
Patch afe860ae deferred freeing the io_device. However, for nvme, the
io_device context (spdk_nvme_ctrlr) is still being destructed before
io_channels are destroyed, causing segfaults on hotremove.

This patch defers io_device context destruction and fixes nvme
hotremove.

Fixes: afe860aeb1 ("channel: Correctly defer unregisters if channels exist")
Fixes: 5533c3d208 ("util: defer put_io_channel")

ce4fcbce71 nvme: add I/O qpair creation options
Add a new struct spdk_nvme_io_qpair_opts to allow the user to override
controller options on a per-I/O qpair basis.

Existing callers with qprio == 0 can be updated to:

  ... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, NULL, 0);

Callers that need to specify a non-default qprio should be updated to:

  struct spdk_nvme_io_qpair_opts opts;
  spdk_nvme_ctrlr_get_default_io_qpair_opts(ctrlr, &opts, sizeof(opts));
  opts.qprio = SPDK_NVME_QPRIO_...;
  ... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, &opts, sizeof(opts));

f71447e80d bdev: remove differentiation between bdev and vbdev modules
We still will sort the bdev_module list so that modules
with an examine() callback are initialized first.  This ensures
they have a chance to initialize before later modules start
registering physical block devices.

7fefd60fab bdev: make module init synchronous again
Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O.  But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.

So simplify the bdev code and modules to go back to
a synchronous init procedure.
