[1]. A trivial code refine in memblock_is_region_memory(), which removes an unnecessary check on base address. [2]. The original code forgets to check the return value of memblock_reserve(), which may lead to potential problem. The patch fix this. --- v3: * remove the check for base instead of comment out * Reform the changelog v2: * remove a trivial code refine, which is already fixed in upstream Wei Yang (2): mm/memblock.c: trivial code refine in memblock_is_region_memory() mm/memblock.c: check return value of memblock_reserve() in memblock_virt_alloc_internal() include/linux/memblock.h | 5 ++--- mm/memblock.c | 8 +++----- 2 files changed, 5 insertions(+), 8 deletions(-) -- 1.7.9.5
