From 425b5dafc8738d3d6d6b05827f40bd32bf04a20b Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Tue, 18 Mar 2014 17:56:06 +0000 Subject: [PATCH] Btrfs: remove unnecessary inode generation lookup in send No need to search in the send tree for the generation number of the inode, we already have it in the recorded_ref structure passed to us.
