From 5f175898dedb2bb2635d4d1dcb2afa8c420d5eae Mon Sep 17 00:00:00 2001
From: NeilBrown <neilb@suse.de>

Subject: Increase default chunk size to 512K

This seems more appropriate for current (and recent) model drives than
64K.
64K is still the default for '--build' as changing that could corrupt
data.
64K is also the default rounding for 'linear' on kernels older than
2.6.16.
