[PATCH 4/5] Rename GFP_HIGH_MOVABLE to GFP_HIGHUSER_MOVABLE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



__GFP_HIGH are used to flag allocations that can access emergency
pools. GFP_HIGH_MOVABLE has little to do with __GFP_HIGH and the name is
misleading. This patch renames GFP_HIGH_MOVABLE to GFP_HIGHUSER_MOVABLE so
that it is clearer.
