Subject: crashblk: a block device crash emulator.

Hi all,

I'm developing 'crashblk'.
It is a memory block device driver to emulate crash, IO error,
and various response time.

The source code repository is here:
https://github.com/starpos/crashblk/

It is very useful to test wrapper block device drivers,
and must be useful to test filesystems also.
I used it to test WalB (https://walb-linux.github.io/),
which is a wrapper block device driver for backup and asynchronous
replication, and found/confirmed several bugs.

If you are interested in crashblk, try it and give me feedback!
Thank you.

Takashi
