// mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM
//
// __GFP_WAIT was used to signal that the caller was in atomic
// context and could not sleep. Now it is possible to
// distinguish between true atomic context and callers that are
// not willing to sleep. The latter should clear
// __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing
// __GFP_WAIT behaves differently, there is a risk that people
// will clear the wrong flags. This patch renames __GFP_WAIT to
// __GFP_RECLAIM to clearly indicate what it does -- setting it
// allows all reclaim activity, clearing them prevents it.
//
// Handle the rename by defining __GFP_WAIT as __GFP_RECLAIM.
