From 55de8b9c60f2f6da9bf5c9144020882d07e62296 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 5 Apr 2018 16:20:29 -0700 Subject: slab: make create_kmalloc_cache() work with 32-bit sizes KMALLOC_MAX_CACHE_SIZE is 32-bit so is the largest kmalloc cache size. Christoph said: : : Ok SLABs maximum allocation size is limited to 32M (see : include/linux/slab.h: : : #define KMALLOC_SHIFT_HIGH ((MAX_ORDER + PAGE_SHIFT - 1) <= 25 ? \ : (MAX_ORDER + PAGE_SHIFT - 1) : 25) : : And SLUB/SLOB pass all larger requests to the page allocator anyways.
