From f0de181c9b48a397c5a2fbe63dcdd2a26a872695 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 17 Sep 2013 10:55:51 -0400 Subject: Btrfs: kill delay_iput arg to the wait_ordered functions This is a left over of how we used to wait for ordered extents, which was to grab the inode and then run filemap flush on it. However if we have an ordered extent then we already are holding a ref on the inode, and we just use btrfs_start_ordered_extent anyway, so there is no reason to have an extra ref on the inode to start work on the ordered extent.
