Are you sure this is the answer to OP's question? Apparently he
placed a FAQ which comes up regularly, i.e. how to monitor disk
activity on process (or kernel thread) level.
Especially with journaling file systems users tend to notice regular
disk activity without knowing which process might cause this. Afaik, it's
been a long standing issue that there's effectively no known tool
which allows disk activity monitoring including process attribution,
maybe even without kernel patching. And htop, I'm afraid, doesn't
offer that capability either.
If anybody knows more, I'd be interested as well.
