Greetings.

 About a week ago I released mdadm-3.1
 I have now 'withdrawn' it meaning that it doesn't appear on the
 kernel.org mirrors any more, and I ask people not to use it.

Although the cause for this sucks, I was actually going to suggest that
since 3.1 is a version bump, that we take the opportunity to change a
few defaults.  Like switching to version 1 superblocks instead of
version 0 by default.  And changing the default chunk size to 512k
instead of 64k.  The time has simply come for the 0->1 superblock
change, and I have a good deal of data showing that for SATA disks at
least, the 512k chunk size is the typical sweet  spot.
