From f971fe29b14eedd4abc389593b77fbdf94ac2d59 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 10 Jun 2013 11:52:32 -0400 Subject: [PATCH] Btrfs: wake up delayed ref flushing waiters on abort I hit a deadlock because we aborted when flushing delayed refs but didn't wake any of the other flushers up and so everybody was just sleeping forever. This should fix the problem.
