[lvm-devel] [PATCH] lvm2: honor yes and force option by lvconvert

[Takahiro Yasui]

This patch suppresses a following prompt by lvconvert command
when --yes or --force option is specified. 

Full resync required to convert inactive mirror <lv> to core log. Proceed? [y/n]:

This change is useful when lvconvert command is used in a script
and a test case.
