I didn't know tests/f_large_dir exists. Thanks for the pointer. There are
just two problems with this:

1) I wanted to test both with & without metadata_csum because the code
paths are somewhat different.

2) Currently we don't have implemented conversion of normal dir into
indexed one so I need to start with a fs image that already has indexed
directory.

I suppose I could modify tests/f_large_dir to start with an image to
address 2) if people are OK with that. And I could just create
tests/f_large_dir_csum to address 1).
