From 050006a753bab8ba05f2113cc57ba49398cd5521 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Fri, 29 Oct 2010 15:37:33 -0400 Subject: [PATCH] Btrfs: fix clone ioctl where range is adjacent to extent We had an edge case issue where the requested range was just following an existing extent. Instead of skipping to the next extent, we used the previous one which lead to having zero sized extents.
