Thanks, this seems to have fixed it.

I tested the OMP version several times (--test=0, --test; with and
without --format=...), and eCryptfs never failed, while some of the 3
dynamic formats still fail in every test run.

I had a look at your changes.
You use ECRYPTFS_DEFAULT_NUM_HASH_ITERATIONS. The name seems to indicate
that the number of iterations can be configured.
If this is indeed true (no idea, since I don't know eCryptfs), shouldn't
the hash include the number of iterations, even if all 3 test hashes in
ecryptfs_fmt_plug.c use the default number of iterations?
