The reason was that my dev tree was tainted by this bug:
if (good_bytes && - scsi_end_request(cmd, 1, good_bytes, !!result) == NULL) + scsi_end_request(cmd, 1, good_bytes, result == 0) == NULL) return;
in scsi_io_completion(). I had there !!result which is wrong, and when I diffed against master, it produced a bad patch.
As James mentioned one of the chunks is good and can go in.
