The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired

Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.

This is no longer used anywhere. For the places where we previously
used it, we've since found alternate solutions that do not

Or rather, at least assert that the allocation failed.
This is not a recoverable error in general.

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.
