From: Thomas Gleixner The deprecation of the SA_xxx interrupt flags did not emit deprecated warnings. Andrew said about the removal of the deprecated flag defines: > This is going to break a lot of external stuff. We should have found > a way to make usage of SA_* emit deprecated warnings (or _some_ > warning) to warn people of impending doom. But I can't immediately > find a way of doing that. if we _can_ find a way of doing this, I > suspect we'll need to do it, and give people another six months. It's > going to get ugly out there. We shall see... Define the deprecated flags as a call to a __deprecated inline function so a warning is emitted on compile time. Extend the reprieve of out of tree drivers to 9/2007.
