From 996d282c7ff470f150a467eb4815b90159d04c47 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 23 Apr 2012 20:35:03 -0400 Subject: Btrfs: do not start delalloc inodes during sync btrfs_start_delalloc_inodes will just walk the list of delalloc inodes and start writing them out, but it doesn't splice the list or anything so as long as somebody is doing work on the box you could end up in this section _forever_. So just remove it, it's not needed anyway since sync will start writeback on all inodes anyway, all we need to do is wait for ordered extents and then we can commit the transaction. In my horrible torture test sync goes from taking 4 minutes to about 1.5 minutes.
