SPDK 19.01.1 is a bug fix and maintenance release.

logical volumes

Added option to change method for erasing data region on lvol store creation.
Default of unmapping can now be changed to writing zeroes or no operation.

autotest

Introduce SPDK_RUN_FUNCTIONAL_TEST variable enabled by default, that can be
manually disabled on systems where e.g. only unit tests are run.

FTL

Add detection for OpenChannel devices, so that NVMe tests and FTL bdev tests
are run on appropriate devices.

QoS

Enabled rate limit when opening the bdev, as there were some cases where
previously closed bdev would have QoS disabled.
