Hmmm... the unconditional retry on ATA_QCFLAG_IO is intenttional so
that known good requests from FS are guaranteed to be retried no
matter how whacky the underlying device is. I'm not sure whether that
was a good decision tho. Maybe we should trust the hardware a bit
more. So, I'm not necessarily against changing it.
Thanks.
