ore: Make ore_striping_info and ore_calc_stripe_info public
Boaz Harrosh [Wed, 10 Aug 2011 21:17:28 +0000 (14:17 -0700)]
The struct ore_striping_info will be used later in other
structures. And ore_calc_stripe_info as well. Rename them
make struct ore_striping_info public. ore_calc_stripe_info
is still static, will be made public on first use.
