There's this Russian dude that has been trying to submit an ISDB-T card driver to Linux for years (but has no idea how kernel development works). Someone else wrote their own driver and upstreamed it. Now he's submitting patchsets that replace the existing driver with his own.

Is he russian? Github says he's from Tokyo (and his repos have Japanese writing).

Not sure; he writes his name in Cyrillic and his, er, interactions on kernel mailing lists don't particularly strike me as typical Japanese. I think he might be an expat living in Japan?

Perhaps. I just got curious because the name isn't Russian at all, but could sound Japanese with proper accents.

He romanizes it as Budi Rachmanto on headers. Indonesian? Definitely not a Japanese name.

No that's definitely a Slavic-origin name, or at least a partial abbreviation of one.

All the hits I'm getting for Rachmanto are for Indonesia, hence my guess.

Seeing Budi Rachmanto & the http://are.ma  domain makes me guess they are Indonesian and originally from Malang, East Java. (Arema is a common abbreviation for Arek Malang = People of Malang)
