Subject: md/raid10: fix transcription error in calc_sectors conversion.
X-Git-Tag: firefly_0821_release~3680^2~2788^2~56
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=b0d634d5683f0b186b242ce6a4f3b041edb8b956;p=firefly-linux-kernel-4.4.55.git

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.
