From 00d71c9c17b1fd28fa54f323a29a0e23c6d3de40 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().
