9c35e39c54 event: Move spdk_poller_register to io_channel
Make this generic and not directly dependent on
the event framework. That way our libraries can
register pollers without adding a dependency.

ec3c0bb2f0 Revert "fio_plugin: allow stopping poller after it's thread has been stopped"
Now that there's a fio_thread
at the time of calling spdk_bdev_finish,
this work-around is no longer
necessary.

This reverts commit ae0f518e4ff841de9835b8994f17542c980df0a5.

a658245f40 fio_plugin: add persistent fio_thread for spdk init/finish
This patch also replaces "temporary"
SPDK threads for init/finish with a
single persistent thread that's created
at the time of init, and destroyed
at the time of finish.

8865e0bf51 fio_plugin: poll all remaining events on thread shutdown
There were unprocessed events in the event ring at the time
of destroying it's thread.

Polling until *done* flag is set is not sufficient. Since a single
fio_getevents call will poll only a single message, any
message positioned after the callback that sets the *done*
flag would not be processed.

11104c1c85 fio_plugin: add back bdev and copy engine finish
During SPDK asynchronous finish cleaning up of bdev and
copy engine was removed. Now it is added back taking
into account asynchronous nature of those two calls.

Only when spdk environment was initialized, on fio_exit
SPDK environment is cleaned up. Similar to init path,
this is done in temporary SPDK thread.

When in here, fixed fio_thread->iocq memleak.

6c54c13cd4 event/subsystem/bdev: asynchronous SPDK finish
First this change moves spdk_subsystem_fini() to trigger on
spdk_app_stop(). This ensures that spdk_subsystem_fini() is called
before reactors are stopped in spdk_reactors_stop().

Finish paths for subsystems, bdevs and copy engine is now
asynchronous.
Each of those three mentioned have to make sure they are
asynchronous as well.

Only bdev that currently has requirement for asynchronous finish
are logical volume.
Thus the change in vbdev_lvol.c making it move to next bdev module
only after all lvol stores were unloaded.

Fio_plugin finish of bdev and copy_engine was removed for now.
Next patch in series adds it back with async support.

8eef5183d3 bdev: remove spdk_bdev_poller_start() lcore option
Always start bdev pollers on the calling core.

This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.

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.

ae0f518e4f fio_plugin: allow stopping poller after it's thread has been stopped
Patch 2b37c71 [1] introduced the
spdk_bdev_finish() call on the
fio_plugin shutdown. That happens
after all the fio threads have
stopped. Patch 19ddb10 [2] introduces
an extra poller that has to be
stopped during spdk_bdev_finish().
Prior to this patch fio_plugin
pollers couldn't be stopped if their
corresponding threads have been
already stopped - but that's a
behavior we want.

[2] 19ddb10 ("bdev_virtio: implement controlq and RESETs")
