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.
