From ad3d5d2f7deca6d0fd72163573bcb0cca6337e33 Mon Sep 17 00:00:00 2001 From: Toshi Kikuchi Date: Thu, 12 Feb 2015 15:02:18 -0800 Subject: lib/genalloc.c: fix the end addr check in addr_in_gen_pool() Since chunk->end_addr is (chunk->start_addr + size - 1), the end address to compare should be (start + size - 1).
