From Documentation/kasan.txt:

therefore you will need a certain version of GCC > 4.9.2

AFAIK gcc 4.9.3 hasn't been released yet. (Or does it mean >= 4.9.2 ?)

Can we perhaps wait until there is a released version of GCC that supports
KASan? And maybe then a touch longer so folks can test it works on their
platforms?
