Ok, looks good as well. I still think we should have the WARN_ON()
in sg_set_buf(), but I can send a separate patch for that to linux-mm.
Please CC me and linux-ide on all libata patches (certainly akpm as
well). Andrew picks up most of the libata changes automatically via git
from my libata-dev.git#ALL.
