Description

Improve partitionAlloc's resistance to fragmentation. If we make a full partition page non-full, take steps to get it filled up again because it is unlikely to become fully empty any time soon. If we make a partition page empty, free it right away under more situations. In the process, also apply some tidy-ups and simplifications. Pulling at this thread led to stronger ASSERTs in the allocation slow path, and better unit test coverage. Committed: https://src.chromium.org/viewvc/blink?view=rev&revision=159297
