The above commit log speaks of LUKS volumes,what about plain and cryptsetup
volumes? The return code for LUKS is vague too since the log is not clear.

I remember asking a way to know if the underlying devise is gone but my
request went unaswered,i therefore use the following hack in line 97 and 98
in the below source file to know.It would be nice if there was an official
way for all three types.
