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.

Cleaner requires adopting trylock() because in current version
cleaner uses management lock when performs cleaning,

WriteBack mode is fully functional after this change,

This patch uses our own mutex to achieve that because we cannot rely on

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.

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.

Two quick updates, support dequeueing more than 1 IO at a time which
is now more likely given that we can queue up compression operations
(others can come in qhile one is on the queue).
Dropped the max inflight value as it was in there as a palceholder
and now it makes sense to give it a sane value. Also updated the value
passed to reduce to signal an error.
UT for the poller will come in the next patch...

If it is 0 then we queue the compression operation up and try

We will also queue if we can't get an mbuf or op from our pools.

how we allocated and freed both the pool and the mbufs.
This also fixes an issue that I hadn't addressed yet with freeing
chained mbufs. Use of the mbuf macro to free them instead of the
generic spdk functions takes care of that for us.

destruct_called is set to true in both of
- destroy_raid_bdev RPC
- hot removal of any base bdev.
If destruct_called is set in destroy_raid_bdev RPC, destroy_raid_bdev
RPC must return immediately, but if destruct_called is set in hot
removal of any base bdev, destroy_raid_bdev RPC must go forward
with the current logic.
Hence add another flag destroy_started to struct raid_bdev and

Currently, if the Bdev subsystem initialization fails, the initialization failed
module does not call the fini function cleanup resource.
However, null module use the 'spdk_io_device_register' and spdk_zmalloc to request
resources. In failed path, it will cause resource leak when exiting the app.
To avoid this, it will cleanup resources when module initialization fails.

Bdev descriptors could be closed only from the same thread
that opened them. This restriction was suddenly introduced
at one point without making sure all the SPDK code respects
it. Vhost can still close descriptors from any arbitrary
thread and fixing that would require some more effort.
With this patch we remove the thread-specific assert from
spdk_bdev_close() and hence allow vhost to work properly
in debug builds. Vhost can still have a possible data
race with bdev hotremove notification, but let's get rid
of the abort() from the usual code path first.

We used to wait only for those descriptors which
specified the hotremove notification callback. The
bdev could've been removed before the descriptor
was closed and the subsequent spdk_bdev_close would
simply segfault.
This patch modifies spdk_bdev_unregister to always
wait for all descriptors to be closed before actually
unregistering the bdev. This consolidates the bdev
unregister behavior for descriptors with and without
the hotremove callback.

Implementation is based adding additional optional argument "name"

Backward compatability of RPC interface is preserved.
This patch also adds tests for the case when name is given.
