mm/slob: Use free_page instead of put_page for page-size kmalloc allocations
When freeing objects, the slob allocator currently free empty pages calling __free_pages(). However, page-size kmallocs are disposed using put_page() instead. It makes no sense to call put_page() for kernel pages that are provided by the object allocator, so we shouldn't be doing this ourselves. This is based on: commit d9b7f22623b5fa9cc189581dcdfb2ac605933bf4 Author: Glauber Costa <> slub: use free_page instead of put_page for freeing kmalloc allocation Cc: Christoph Lameter <> Cc: Pekka Enberg <> Cc: Matt Mackall <> Acked-by: Glauber Costa <> Signed-off-by: Ezequiel Garcia <> Signed-off-by: Pekka Enberg <>
