From 24bbcf0442ee04660a5a030efdbb6d03f1c275cb Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Thu, 12 Nov 2009 09:36:34 +0000 Subject: Btrfs: Add delayed iput iput() can trigger new transactions if we are dropping the final reference, so calling it in btrfs_commit_transaction may end up deadlock. This patch adds delayed iput to avoid the issue.
