    Description

      Since vmalloc allocations are notoriously unscalable and slow, we should do what other filesystems are doing (and what we converted upstream kernel client to do) and for large allocations we should always try kmalloc first (with NOWARN flag) and then if that fails, retry with vmalloc.
