Now that the SLUB seems to be fixed so that it respects the requested alignment, use kmem_cache_alloc() to allocator if the block size of the buffer heads to be allocated is less than the page size. Previously, we were using 16k page on a Power system for each buffer, even when the file system was using 1k or 4k block size. Signed-off-by:
