The patch titled Subject: mm/page_alloc: add a VM_BUG in __free_one_page() if the zone is uninitialized. has been removed from the -mm tree. Its filename was mm-page_alloc-add-a-vm_bug-in-__free_one_page-if-the-zone-is-uninitialized.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Cody P Schafer <cody@xxxxxxxxxxxxxxxxxx> Subject: mm/page_alloc: add a VM_BUG in __free_one_page() if the zone is uninitialized. Freeing pages to uninitialized zones is not handled by __free_one_page(), and should never happen when the code is correct. Ran into this while writing some code that dynamically onlines extra zones.
