From 3530538d9662bb967c26e0113e6e4587018682c1 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Mon, 4 Mar 2013 09:45:06 +0000 Subject: [PATCH] Btrfs: fix unclosed transaction handler when the async transaction commitment fails If the async transaction commitment failed, we need close the current transaction handler, or the current transaction will be blocked to commit because of this orphan handler. We fix the problem by doing sync transaction commitment, that is to invoke btrfs_commit_transaction().
