Description Andreas Kleen 2006-03-06 20:18:52 UTC 
I don't have any MD devices configured, but I get on reboot on the serial
console. It should only print such a message for an actually existing
MD device

MAtch to make md quiet

Whenever an md device is opened, the internal data structures are created.  The above suggests that the first 32 devices were openned.  This is presumably done in some boot script, but shouldn't be needed.

The attached patch - which is now in HEAD - will remove the unpleasant, and unnecessary - messages.
Comment 2 Neil Brown 2006-03-07 03:54:00 UTC 
It seems I cannot resolve without a comment, so:

 The above patch should fix the problem.
