The best way is either this mailing list or create new issue or merge request
on the gitlab project pages (https://gitlab.com/cryptsetup/cryptsetup).
Github has mirror of repo so you can also create merge request there
as well (https://github.com/mbroz/cryptsetup)

How big is that keyfile? (And what is underlying storage?)
Just wonder why it is so slow...
Anyway, patches look good, I will commit it later.

The testsuite is just bunch of bash script that runs after "make check"
(and also they run in Travis on Github automatically).
It should be quite easy to add your tests but I think I have most of the
magic with handling EOL etc already there (at least for keyfile on stdin).
