What exactly is going on here?  Why do you have to go through so many
iterations just reformatting again and again and again?

Indentation by TAB only, please.

Please just to:

	subvolname[0] = '\0';

Can you please use puts() instead of print() for all output that does

Is this imported code?
CodingStyle says to use braces in all branches if not all branches of
a conditional statement are single line statements.  This should be
fixed globally.

Is this imported code? Otherwise: can we drop these empty lines before
the returns?

Ditto.

Ditto. etc.  This should be fixed globally.
