Btrfs: fix possible empty list access when flushing the delalloc inodes We didn't have a lock to protect the access to the delalloc inodes list, that is we might access a empty delalloc inodes list if someone start flushing delalloc inodes because the delalloc inodes were moved into a other list temporarily. Fix it by wrapping the access with a lock. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: Josef Bacik <jbacik@fb.com>
