From d006a04816a306995cd9d394079652a7462f81f8 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Tue, 12 Nov 2013 20:54:09 -0500 Subject: [PATCH] Btrfs: only drop modified extents if we logged the whole inode If we fsync, seek and write, rename and then fsync again we will lose the modified hole extent because the rename will drop all of the modified extents since we didn't do the fast search. We need to only drop the modified extents if we didn't do the fast search and we were logging the entire inode as we don't need them anymore, otherwise this is being premature.
