Jens,

here are some simple bio related cleanups.  Any thoughts?  Can those go
in via your tree?

Thanks,
Andreas

Hello Andreas, during blktests CI trial runs, I noticed that this patch series
triggered failures of three blktests test cases: scsi/004, scsi/007 and
throtl/004. Do you see which patch triggered these failures?

Hello Shinichiro,

thanks a lot for the report. I now see that patch "block: get rid of
blk_status_to_{errno,str} inconsistency" is broken in its current
form.
