Page Alloc Hogger Lets You Better Stress Memory Behavior On Linux For Testing/Debugging Written by Michael Larabel in Linux Kernel on 6 August 2026 at 06:28 AM EDT. Add A Comment A new kernel feature proposed by a Google engineer is Page Alloc Hogger to allow for fine control over where memory pages are allocated in order to more easily reproduce low-memory conditions, make it simpler to exert memory pressure, and enable other stressful memory conditions for testing/debugging how Linux copes. Juan Yescas of Google sent out the patches for Page Alloc Hogger to let the user (developer) be able to allocate memory pages from specific nodes, zones, migration types, and orders. This control is granted via DebugFS and aims to provide a number of testing and debugging benefits.
