7bb007d206 lib/bdev: Expose DIF type and location of bdev.
This patch is for DIF settings.

Add fields dif_type and dif_is_head_of_md to struct spdk_bdev and
add APIs spdk_bdev_get_dif_type and spdk_bdev_is_dif_head_of_md to
bdev APIs.

The fields dif_type and dif_is_head_of_md are added to the JSON
information dump.

139da44c43 lib/bdev: Expose metadata size and setting of bdev
To support DIF, bdev will need to expose the following information:
- Metadata format
 - Block size
 - Metadata size
 - Metadata setting (interleave or separate)
- DIF settings
 - DIF type 1, 2, or 3
 - DIF location
- DIF check types
 - Guard check
 - Reference tag check
 - Application tag check

This patch is for the metadata format. Subsequent patches will do for the DIF
setting and DIF check types.

Add fields, md_len and md_interleave, to struct spdk_bdev and add APIs,
spdk_bdev_get_md_size and spdk_bdev_is_md_interleaved, to bdev APIs.

The fields, md_len and md_interleave, are added to the bdev JSON infomation dump.

DIF will be used only in the NVMe bdev module and the upcoming virtual
DIF bdev module first. But additional required storage by md_len and md_interleave
will be very small and they are simple. Hence add them to struct spdk_bdev simply.

ff182630dc bdev: explicitly mark _spdk_bdev_io_submit as inline
This function gets used as a function pointer, which
seems to keep the compiler from trying to inline the
function.  Stack manipulation was showing up in the
perf profile pointing to this.  Marking the function
as inline gets it actually inlined in the hot I/O
path.

Improves bdevperf microbenchmark from 78M to 85M IO/s.
Cores are virtually identical - 11.4M on core 0 and
10.4-10.6M on remaining cores.

0744f10860 bdev/gpt: support parsing secondary partition table
Modify existing code of parsing primary partition table to support parsing
the secondary.

Main difference of these two tables is that they have inverse buffer layout.
For primary table, header is in front of partition entries. And for secondary
table, header is after partition entries. So add helper functions to extract
header and partition entries buffer region from primary or secondary table
based on current parse phase.

Split the exported funtion spdk_gpt_parse into two functions spdk_gpt_parse_mbr
and spdk_gpt_parse_partition_table. So spdk_gpt_parse_partition_table could be
used to parse both primary and secondary table.

abc156458f bdev: mark delete_bdev RPC deprecated
This RPC doesn't really work in some cases - for example,
trying to delete one NVMe namespace bdev from a controller
with multiple namespaces, or just one virtio SCSI device
from a virtio-scsi controller.  We've previously kept it
and marked it as "debugging only" - but every bdev module
has its own RPC method now for deleting what it constructed,
so keeping the generic delete_bdev RPC is asking for
trouble in some of the cases mentioned above.  We'll remove
it in the 19.04 release.

d3bfd244f0 bdev/aio: unregister io_device correctly
The io_device associated with the aio bdev was only
getting unregistered when the aio bdev was explicitly
deleted - not in the implicit deletion path at shutdown.

Move the io_device_unregister into the destruct_cb -
this makes sure the io_device is always unregistered, whether
the bdev is getting unregistered via an explicit RPC or
implicitly in the shutdown path.

Fixes #618.

b78e763c1a string: spdk_strtol to delegate additional error checking
Error check of strtol is left to users of it. But some use cases
of strtol in SPDK do not have enough error check yet.

For example, strtol returns 0 if there were no digits at all.

It should be avoided for each use case to add enough error checking
for strtol.

Hence spdk_strtol and spdk_strtoll do additional error checking
according to the description of manual of strtol.

Besides, there is no use case of negative number now, and to keep
simplicity, spdk_trtol and spdk_strtoll allows only strings that
is positive number or zero.

As a result of this policy, callers of them only have to check if
the return value is not negative.

Subsequent patches will replace atoi to spdk_strtol because atoi
does not have error check.

d1fee489a7 OCF: add OCF module
Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
  caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf

With this patch OCF-enabled device is represented in SPDK
  as virtual bdev having core and caching devices as its base devices

This patch includes implementation of:
  * OCF top adapter          (vbdev_ocf.c)
  * OCF bottom adapter       (dobj.c, data.c)
  * Adaptation layer for OCF (env/)
  * OCF context abstractions (ctx.c)

Adaptation layer and context abstractions are not dependent on SPDK bdev

OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches

ec415110c1 bdev: avoid qos submission recursion
_spdk_bdev_io_submit uses the bdev_io->internal.in_submit_request
flag to ensure we unwind in cases where the I/O is completed
inline (i.e. malloc or null bdevs).  But when an I/O gets queued
for QoS, and then we iterate through the queued I/O in
_spdk_bdev_qos_io_submit(), this flag was not getting set
when those I/O would get submitted to the underlying bdev.  This
would allow for _spdk_bdev_qos_io_submit recursion, resulting
in all kinds of different types of memory corruption.

Fixes #613.

encryption haven't respected it.

We now allocate those buffers with the crypto bdev's
required alignment. It is only required for QAT and we
do it unconditionally, but we don't want to strcmp the
driver name in the hot I/O path just for that - the
code is to be refactored anyway.
