[lvm-devel] [LVM2 PATCH] Fix 'lvconvert -s' to work again

[Jun'ichi Nomura]

Hi,

In current CVS head, 'lvconvert -s' doesn't work.
 # lvconvert -s testvg/lvol0 testvg/lvol1
 --snapshots argument cannot be mixed with --mirrors or --log
 lvconvert: Change logical volume layout

This is due to the lvconvert parameter check uses
'count' variable uninitialized for non-mirror case.
        int count;
...
        if (arg_count(cmd, log_ARG) || arg_count(cmd, mirrors_ARG))
                count = 1;
        count += arg_count(cmd, snapshot_ARG);

While the code around the _read_params() could be tidied up
some more, I hope this fix is included for now.

Thanks,
