X-Git-Tag: v2.6.30-rc1~241^2~12 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fef9c61fdfabf97a307c2cf3621a6949f0a4b995;p=pandora-kernel.git md/raid5: change reshape-progress measurement to cope with reshaping backwards. When reducing the number of devices in a raid4/5/6, the reshape process has to start at the end of the array and work down to the beginning. So we need to handle expand_progress and expand_lo differently. This patch renames "expand_progress" and "expand_lo" to avoid the implication that anything is getting bigger (expand->reshape) and every place they are used, we make sure that they are used the right way depending on whether delta_disks is positive or negative.
