From deae60a087fceb3418efb8dd23ab557b767f925a Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Mon, 5 Mar 2012 08:49:34 +0100 Subject: [PATCH] e2fsck: do not forget to discard last block group Previously when running e2fsck with '-E discard' argument the end of the last group has not been discarded. This patch fixes it so we always discard the end of the last group if needed.
