From 5cac6bcb9312a18a5091976fc374b4c7b9c4ae2e Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Fri, 17 Jul 2015 12:17:50 +1000 Subject: md/raid5: always set conf->prev_chunk_sectors and ->prev_algo These aren't really needed when no reshape is happening, but it is safer to have them always set to a meaningful value. The next patch will use ->prev_chunk_sectors without checking if a reshape is happening (because that makes the code simpler), and this patch makes that safe.
