I can confirm that the patch works and the compiled drbd module woks as expected.

Wouldn't it be a good idea to include the changes from 0.7.22 and/or 0.7.23 to the upcoming stable etch release? It seems that the debian 0.7.21 package hasn't been tested that much with kernel 2.6.18 anyway (because it could no be build). -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
