[dm-devel] Re: dm targets with spaces in the name

I can't guarantee that names with spaces in them have had much testing
as LVM doesn't permit them.  But device-mapper itself and dmsetup
are supposed to support them.

Tools really should not be passing path names into constructors - use the
major:minor format instead as the in-kernel code paths are much more
predictable, there are fewer opportunities for races and so it offers
better control to the userspace code.
