From f2257a56eeb4afb3daea894baf93077af0579586 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 14 Jul 2011 16:00:40 +0200 Subject: [PATCH] drbd: Allow to create devices with a minor number > minor_count The minor_count module/kernel parameter serves to scale the size of drbd's internal memory pool, but it is no longer a limit for the number of minors or the minor number. (Minor numbers can be arbitrarily high within the allowed limit of 2^20.)
