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.

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.

check preventing some vhost sessions from being initialized.
It will be necessary for virtio-vhost-user, whose memory comes
from PCI BARs and its size may not be a 2MB multiple.

Currently, we translate each 2MB chunk to manually check
if it's contiguous with the previous one, but there are
rte_vhost APIs that do it way more efficiently.
rte_vhost_va_from_guest_pa() was introduced in DPDK 18.02,
but was backported to 17.11 as well, so we don't even need
any RTE_VERSION ifdefs to use it now. This function
calculates the remaining region size instead of trying to
translate subsequent 2MB chunks over and over.
The previous rte_vhost_gpa_to_vva() was deprecated a long
time ago and after this patch we no longer make any use of
it.
DPDK usages of this new function check if the translated
memory region has 0 length, which seems very silly, but
let's just do it in SPDK as well.

The compressdev enqueue call will return the number of ops that
it was able to accept. By design this will always be 1 for our
implementation so check that to make sure.
If it is 0 then we queue the compression operation up and try
again after something is dequeued in the poller.
We will also queue if we can't get an mbuf or op from our pools.

The new, simplified scsi lun hotremove path doesn't call
lun->hotremove_cb if there's no io_channel allocated for
that lun. Vhost still depends on that callback and currently,
when the underlying bdev is removed, vhost is left completely
unnotified. It keeps a dangling pointer to a scsi lun and
will eventually crash. The vhost scsi controller also can't
be removed in this case.
This reverts commit 19182431c8.

struct dif_sgl had been used only to iterate the passed iovec

function _dif_sgl_append() to simplify to create iovec array.
_dif_sgl_append() is a static function and we have to add
the callee together when we add any static function.
So this patch adds both even if the patch size is a little
larger.
Besides, iovcnt has been used to mean the number of elements
in the iovec array widely in the DIF library. So this patch
changes the name of it from num_iovs to iovcnt.

Currently the nvme driver will always log any
request completed with error status. Some
applications may not want this behavior. So provide
an option to disable it at the controller level.
When this option is enabled, any failed requests
from queues associated with that controller
(including the admin queue) will not log the
failed request.
Of course the application will still receive
the failed status code and can decide to do its
own logging there.

In working on a future patch to queue compress operations, I found
some corruptions in our mbuf pool stemming from an inconsistency
in using mbuf macros when constructing a compress operation and
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.

We have observed unexpcted timeout when we remove LUNs from the
active iSCSI target dynamically during FIO workload.
By making destroy_raid_bdev RPC wait for its completion, we could know
the destroy_raid_bdev RPC caused timeout because LUN hot removal didn't
complete.
By investigating the log, incoming I/Os from the host had not stopped
even after hot removal process was started.
The reason was that iSCSI target had continued to accept incoming I/Os
from the host.
By removing LUN from the SCSI device at the start of the LUN hot removal
process, iSCSI target will be able to stop incoming I/Os and LUN hot removal
will complete in finite time.
LUN itself can be accessible even after it is removed from the SCSI device.
LUN hot removal is for not I_T nexus but I_T_L nexus and so we cannot
start connection exiting in this case because connection can have multiple
LUNs. So this fix requires few changes and will be practical.

set to spdk_env_get_current_core(), but we won't be able
to use an equivalent get_current_poll_group() function
after we switch to poll groups. We will have a poll group
object only inside spdk_vhost_session_send_event() that's
called from the DPDK rte_vhost thread.
In order to change the lcore field (or a poll group one)
from spdk_vhost_session_send_event(), we'll need a separate
field to maintain the started/stopped status that's only
going to be modified from the session's thread.

The goal is to remove legacy event messages from vhost.
The new message passing API accepts thread objects instead
of lcore numbers and poll groups are meant to simplify
the transition.
Eventually we'd like vhost to spawn its own threads and
do message passing only within those, but SPDK libraries
can't spawn their own threads just yet. As a stopgap, vhost
will now maintain a list of all available threads (in form
of "poll groups" to mimic nvmf) and will start pollers on
them using its own round robin scheduler.
This patch only adds the poll groups list, it doesn't
change any existing functionality.

destruct_called is set to true in both of

- 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

Typically we just pass the bdevs supported IO types
for each of its partitions. But that doesn't work
for partitions with non-zero offsets since we can't
decode/modify the NVMe command in the bdev layer
to account for that offset. So just don't allow it.

We're about to drop legacy event messages from SPDK libs
and for that we'll replace various lcore numbers with
spdk_thread objects. For now SPDK libs can't spawn their
own threads, so they must use spdk_for_each_thread() and
spdk_get_thread() to retrieve different thread pointers.
The vhost library offers API to construct a vhost device
to be polled on specified cores, and in order to keep that
functionality we'll need to know which core each thread
is polling on. We would like to achieve that with
spdk_thread_get_cpumask(), but right now it always returns
all cores, so this patch changes it to return just
a single cpu on which the thread is actually pinned. It's
only a stop gap, eventually the vhost library will spawn
its own threads with custom cpumasks.

Send the given NVM I/O command, I/O buffers, lists and all to
the NVMe controller.
This is a low level interface for submitting I/O commands directly.
This can only be used on PCIe controllers and qpairs.
This function allows a caller to submit an I/O request that is
COMPLETELY pre-defined, right down to the "physical" memory buffers.
It is intended for testing hardware, specifying exact buffer location,
alignment, and offset. It also allows for specific choice of PRP
and SGLs.
The driver sets the CID. EVERYTHING else is assumed set by the caller.
Needless to say, this is potentially extremely dangerous for both the host
(accidental/malicionus storage usage/corruption), and the device.
Thus its intent is for very specific hardware testing and environment
reproduction.
