[dm-devel] [PATCH] dmsetup: fix 'dmsetup status' for crypt filling '0' in wrong area

[Jun'ichi Nomura]

Hi,

dmsetup tries to suppress encryption key of crypt target in the table
by filling '0' in params buffer.
However, the code assumes the case for showing table only and will
fill '0' beyond the params buffer when it's showing status, where
the params is "".

The patch fixes it.
The suppression is not necessary for showing status as
no encryption key is included in status line.

Thanks,
