Test that if we keep overwriting an entire file, either with buffered writes or direct IO writes, the number of used blocks reported by stat(2) is never zero while the writes and writeback are in progress. This is motivated by a bug in btrfs and currently fails on btrfs only. It is fixed a patchset for btrfs that has the following patches: btrfs: fix missing delalloc new bit for new delalloc ranges btrfs: refactor btrfs_drop_extents() to make it easier to extend btrfs: fix race when defragging that leads to unnecessary IO btrfs: update the number of bytes used by an inode atomically Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
