Re: fio execution issue on Android device with MediaTek

[David Nellans <david@nellans.org>]

I may have actually spoken prematurely - if the krait version is running 
v7a and compiles for armeabi-v7a
but the mt6572 is only supports armeabi you could run into ABI issues.  
either way, still very unlikely its a fio issue.
