Someone named "Ugis" on the mailing list was having trouble
with the rbd command. One of the things this person mentioned
was this:

From: Ugis <ugis22@gmail.com>
Subject: rbd kernel module crashes with different kernels
...
well, I do not understand what in doc
(http://ceph.com/docs/master/rbd/rbd-ko/) is meant by "myimage" so I
am ommiting that part, but in no way kernel should crash if wrongly
passed command has been given.
Excerpt from doc:
sudo rbd map foo --pool rbd myimage --id admin --keyring /path/to/keyring
sudo rbd map foo --pool rbd myimage --id admin --keyfile /path/to/file

Anyone can explain what is "foo" and "myimage" meaning here? Wich one
is image name in pool and what is the other for?

I'm pretty sure "foo" is crap. And "myimage" should be "{image-name}"
in order to fit with the context around it.

Please verify this is a problem, though, I'm not an expert in
the usage of the rbd CLI...
