From: Lucas Wei <lucaswei@xxxxxxxxxx> For kernel releases older than 4.20, using the SLUB alloctor will cause this alignment check to fail as that allocator did NOT align kmalloc allocations on a PAGE_SIZE boundry. Remove the check for these older kernels as it is a false-positive and causes problems on many devices.
