1554a344c9 env: Add free_space parameter to spdk_ring_enqueue
DPDK rte_ring_enqueue_bulk() has free_space parameter to return
the amount of space in the ring after enqueue operation has finished.
This parameter can be used to wait when the ring is almost full and
wake up when there is enough space available in the ring.

Hence we add free_space to spdk_ring_enqueue() and spdk_ring_enqueue()
passes it to rte_ring_enqueue_bulk() simply.

493fb55e4c bdev: add _spdk_bdev_io_do_submit function
Move actual submission code to _spdk_bdev_io_do_submit, used by
both normal submission path and QoS path.

Previous patch(review.gerrithub.io/c/442127) adds the missing
bdev_io->internal.in_submit_request flag to QoS submission path.
But QoS submission path doesn't handle nomem_io yet.

This patch makes QoS submission path handle nomem_io in the same way
as the normal path and extracts actual submission code into do_submit
function, so that further modification of the submission logic will
apply to both paths automatically.

4003ebf73c ocf: serialize base bdev names in OCF UUID

  also stored in cache metadata, but we cannot use it
  because its size is limited to 64 bytes.

80a2ff01f3 ocf: implement OCF cleaner
Implement cleaner that is used in WriteBack mode.

Cleaner is a background agent that does synchronization
 of data between cache and its cores.
 Cleaner usually runs every ~20 seconds to perform cleaning.
 The synchronization is a simmilar operation to OCF management flushes.
We need cleaner for WriteBack because only WriteBack mode
 produces dirty data that cleaner needs to deal with.
Cleaner requires adopting trylock() because in current version
 cleaner uses management lock when performs cleaning,
 which may lead to deadlocks if cleaner runs on
 the same thread as management operations.

WriteBack mode is fully functional after this change,
  but persistent metadata support is required to use it for production.

Cleaner will run on management thread for now.
  We plan to implement functionality of
  chosing a CPU core where cleaner should run.
Cleaning policy is not configurable yet.
  The default is ALRU with 20 sec interval.

244d6e3daa ocf: lock queue list during create/delete
OCF queue list needs to be managed synchronously.
This patch uses our own mutex to achieve that because we cannot rely on
  ocf_mngt_cache_lock() as it may produce deadlocks when using
  cleaner.

Alternative way would be to use trylock, but
  we need to register a poller for it and do locking concurently
  which doesn't seem to be possible in callbacks of io channel.

We agreed with OCF team that we are going to change this part
  when OCF will deliver safe ocf_mngt_cache_lock() function.

This patch fixes a very rare failure on our CI that looked like this:

4e7fb25066 ocf: add shared cache instance context
Introduce cache context structure that is going to be used

  cleaner_channel, cleaner_thread.

Lifetime of this structure ends with last vbdev that gets unregistered
  and NOT when cache stops because cache does not have to be freed
  there.

9000deb734 ocf: use trylock in vbdev_ocf.c
Use new trylock API to prevent lockups when using OCF cleaner.
Starting and stoping OCF bdev becomes asynchronous with this patch.

Using trylock means that we have to poll function that does locking each
  time we want to initiate some operation on cache instance.
  This is the reason why management functions become asynchronous.
Each management operation now has a _poll() operation associated with it.
  _poll() uses trylock and continues when cache is locked.

c3d044cbd7 ocf: use vbdev_ocf_mngt_ interface in register path
This patch is a preparation for adopting ocf_cache_trylock() function.
Register OCF bdev path uses vbdev_ocf_mngt_ interface now
Register stays synchronous blocking operation in this patch,
 but with adoption of ocf_cache_trylock() function,
 register will be asynchronous, in which case we
 want to use mngt_ interface.

This series of OCF patches will enable WriteBack support for OCF bdev.
There is a lot of preparation before we will be able
 to actually implement WriteBack.
Dependencies look like this:
- WriteBack
  - Cleaner
    - trylock
  - Persistent metadata
    - asynchronous management API

Cleaner is a background agent that does synchronization
 of data between cache and its cores.
 Cleaner usually runs every ~30 seconds to perform cleaning.
 The synchronization is a simmilar operation to OCF management flushes.
We need cleaner for WriteBack because only WriteBack mode
 produces dirty data that cleaner needs to deal with.
Cleaner requires adopting trylock() because in current version
 cleaner uses management lock when performs cleaning,
 which may lead to deadlocks if cleaner runs on
 the same thread as management operations.

Peristent metadata is functionality of OCF
 that allows to restore cache state after shutdown
We need persistent metadata in context of shutdown
 with some data being dirty which may only happen
 when using WriteBack mode
Support for persistent metadata requieres
 asynchronous OCF API because in current version
 we will have a deadlock during metadata initialization
 because it is required to be done on different thread
 than cache initialization.
