  Build & boot a kernel with the kernel patches I posted ([PATCH 0/3 v2]
ext4: Speedup orphan file handling) - warning there are actually 4 patches
in the series, I just messed up header.

Build e2fsprogs with patches in this series.

Create filesystem with '-O orphan_file' feature.

Now you can test whether the feature makes a difference for things you are
interested in - it may be visible when you heavily delete / truncate files
from lots of processes in parallel.
