From d86477b303da51832002eec1cdec2938c42fccc3 Mon Sep 17 00:00:00 2001 From: Filipe David Borba Manana Date: Thu, 30 Jan 2014 13:27:12 +0000 Subject: Btrfs: add missing error check in incremental send Function wait_for_parent_move() returns negative value if an error happened, 0 if we don't need to wait for the parent's move, and 1 if the wait is needed. Before this change an error return value was being treated like the return value 1, which was not correct.
