f01146ae48 blob: use uint64_t for unmap and write_zeroes lba count
Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.

But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned.  If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks.  Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.

So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries.  But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.

Fixes issue #2190.

e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

d18e63206a mk/lib: add a check that major and minor version is set for libs.
Also, while we are here, consolidate setting SO_SUFFIX to one spot.

Previously, it was possible for a library to slip through
without an SO version.

6569a0ea06 lib/blobfs: add a map file.
Also, increment the library version since some non-public symbols have been removed.

Please note, SPDK_LOG_BLOBFS is included in the map file because it is used by the
blobfs_bdev module.

193927830d make: rev SO versions individually for libraries.
This will allow us to keep track of compatibility issues on a
per-library basis.

1edd9bf3e4 blobfs: Add a lightweight filesystem built on the blobstore
This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.

Also included in this patch:

1) a shim for using SPDK bdevs as the backing store for
   SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
   with RocksDB
3) scripts for running a set of workloads and collecting
   profiling data with RocksDB and blobfs

See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.
