My guess would be the clone change, if raid was not leaking before. I cannot lookup any patches at the moment, as I'm still at the hospital taking care of my new born baby and wife :) But try and reverse the patches to fs/bio.c that mention corruption due to bio_clone and bio->bi_io_vec and see if that cures it. If it does, I know where to look. When did you notice this started to leak?
