06f6c90626 bdev/crypto: add IO queueing for out of mem condition via bdev layer
Also made on the prints a DEBUG message instead and noticed the really
name that was being registered by this component so updated it to
make it look like the rest of SPDK.

457afd77b1 bdev/split: Fix orphan'ed config when removing the base bdev first
When we create a base bdev and then create a split vbdev on top of
the base bdev, if we delete the base bdev first, we have no way to
remove the configuration of the split vbdev. Hence even if we
create a base bdev again, we cannot create any split vbdev on top
of the base bdev again.

The meaning of flag, `removed` of `struct spdk_vbdev_split_config`
is not clear and there will be no issue even if the flag `removed`.

Hence remove the flag `removed` in this patch.

fcbbcf4905 bdev: cleanup child iov rewind code
When we run out of bdev_io's child iovs and we had
to round down I/O size to nearest block size boundary,
we used to decrease the existing child_iovcnt and
set a new "child_iov_run_out" flag to terminate the
uppermost splitting loop.

We can get rid of that new flag by just not decreasing
child_iovcnt when rewinding the last few iovs - it
will make the uppermost loop naturally terminate using
the existing checks.

efd7b514d4 bdev: rewind child offset to last block size aligned iov
Here is the an example to describe existing issue:

There is a Write request with 64KiB data length, and this IO is cross the IO
boundary.  We assume that the parent IO will have 2 children requests, one is
33KiB length, the other one is 31KiB.  Here is the view of parent iovs, the
first 33KiB length data has 33 iovs:

iov.[0].iov_length = 1024;
.
.
iov.[31].iov_length = 256;
iov.[32].iov_length = 768;
.
.
iov.[64].iov_length = 1024;

In function _spdk_bdev_io_split(), then you can see that for the 33KiB length
child request, exiting code will run out of child child_iov space and return
error due to last one data buffer is not block size aligned.

Here we can rewind the existing offset to last block size aligned buffer to
avoid the error case, for backend which need aligned data buffer such as
AIO backend, the request will go through spdk_bdev_io_get_buf() again to
do the data copy, otherwise for those backend devices such as NVMe with
hardware SGL support, 256 data segment is fine for them.

5d718951a6 bdev: split requests first if the request has data buffer
There is one existing example usage case to describe the issue:
Users(e.g. Vhost-blk target with Windows Guest) call spdk_bdev_readv_blocks()
to submit a 128KiB length data READ request, and the data buffer
provides by vhost isn't aligned, but the backend block device
requires aligned data buffer, so existing function call trace:
spdk_bdev_readv_blocks()-->
    spdk_bdev_io_submit()-->
    spdk_bdev_io_get_buf()
spdk_bdev_io_get_buf() will allocate buffer from large data
buffer pool for 128KiB length, of course, it will return error
with existing logic.

So here, no matter what the data length is, we can go through
the split process first for both READ and WRITE.

However, there is one scenario that for iSCSI READ request,
the iSCSI layer will not allocate data buffer for the request,
so for this case if the IO boundary is required we should keep
the logic as before.

There were some TODO items in here that were incorrect if using
an underlying block device that had a 4K block size. The values
here will set the compress vol LBA size to match that of the
underlying lvol but the backing IO unit size, the min size that
reduce will use to perform backing device IO is set to 4K as
smaller than this makes little sense given chunk size is currently
at 16K.

622127d7e1 blobstore: Make possible to remove snapshot if there is only one clone
Starting with this patch it is possible to remove a
snapshot if there is only a one clone created from it.

In such case snapshot can be removed without any data
copying. This is achieved with following steps (case
with only one clone):
1. Open snapshot (Snapshot1) that shall be removed
2. Check if the Snapshot1 has no more than 1 clone (Clone1)
3. Remove Clone1 entry from Snapshot1
4. If the Snapshot1 has a parent snapshot (Snapshot2):
 4a. Add Clone1 entry to the Snapshot2 clones list
 4b. Remove Snapshot1 entry from Snapshot2 clones list
5. Open Clone1 blob
6. Freeze I/O operations on Clone1
7. Temporarily override md_ro flag for Snapshot1 and Clone1
   for MD modification
8. Merge Snapshot1 and Clone1 clusters maps into Clone1
   clusters map
9a. If Snapshot2 is present switch parent ID and backing
    bs_dev on Clone1
9b. If Snapshot2 is not present set parent ID to
    SPDK_BLOBID_INVALID and backing bs_dev to zeroes_dev
10. Sync MD on Clone1
11. Sync MD on Snapshot1
12. Restore MD flags for Clone1 and Snapshot1
13. Unfreeze I/O on Clone1
14. Close Clone1 blob
15. Remove Snapshot1

73204fe2e5 dif: Add data offset to DIF context separately from start block address
Data offset are intended to correspond to DATAO in NVMe/TCP and
Buffer Offset in iSCSI.

Previously for iSCSI, buffer offset had been merged to start block
address, but passing buffer offset separately from start block address
clarifies the logic more.

On the other hand, for NVMe/TCP, passing DATAO separately from start
block address will be critically important because DATAO will bave any
alignment and will be necessary to use for not only reference tag
but also guard computation.

This patch adds data_offset to struct spdk_dif_ctx and adds it to the
parameters of spdk_dif_ctx_init(). ref_tag_offset is also added to struct
spdk_dif_ctx and it is computed by dividing data_offset by data_block_size
and is used to compute reference tag.

The next patch will use this change when getting DIF context in SCSI.

2bfa860dfe ocf: fix offset check
This patch fixes submission of partial IOs in bottom adapter

Existing check (if offset > 0) was not sufficient to detect partial IOs
  because there could be an IO with offset = 0 but length < total size of iovs.
This patch changes the check, but also free operation on completion
  because now the old free does not cover all situations when we allocate iovs.

`Partial IOs` are the IOs handled by bottom adapter
  which specify only part of the internal iovs vector.
So their length is less that the length of internal iovs vector.
They exist because sometimes parts of single IO from top adapter
  need to be sent to different locations.
Also, in general, IOs initiated by OCF (such as cleaner IOs) are represented
  as single big iov that is submitted by parts in form of 'Partial IOs'.

9686948334 ocf: implement metadata probe
Implement metadata probe functionality to load cache state
  from disk.
During metadata probe, we inspect UUIDs of core devices
  and create vbdev configurations based on them.
  Then, to start vbdev, we use load path (loadq = true).

After this change persistent metadata is officially supported,
  we can save and restore cache state from persistant storage.

WriteBack mode is now safe to use in respect to unexpected shutdowns,
  because all information about dirty data is also restored during cache load.

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

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.
