Subject: [PATCH] md/raid10: fix transcription error in calc_sectors
conversion.
The old code was
sector_div(stride, fc);
the new code was
sector_dir(size, conf->near_copies);
'size' is right (the stride various wasn't really needed), but
'fc' means 'far_copies', and that is an important difference.
