From 13f2682b7216ebebd72b3d5868fe7fccec91a92d Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 18 Jun 2009 08:48:55 +1000 Subject: md: raid0/linear: ensure device sizes are rounded to chunk size. This is currently ensured by common code, but it is more reliable to ensure it where it is needed in personality code. All the other personalities that care already round the size to the chunk_size. raid0 and linear are the only hold-outs.
