If I understand this change correctly it removes background zeroing of freed pages. What effect will this have on security? Grsecurity adds a feature which allows the linux kernel to sanitize freed pages[1]. I realize that the idle time freeing isn't the same as the immediate sanitation that grsecurity offers but I'm curious if this change has any effect on security in this manner.
