Did this actually happen to you? Or is this just "good practice" to check the
return value from
nning random read/write test while verifying
data. I also measured performance for current buslogic driver and
buslogic driver with these patches with 32-bit and 64-bit kernel and
ensured there was no degradation in performance.

You are right that EFI specification uses exactly these long names for
the constants, but does that mean kerne
