Eric Dumazet 5e76f56457 dma-debug: increase HASH_SIZE ... With modern NIC, it is not unusual having about ~256,000 active dma mappings and a hash size of 1024 buckets is too small. Forcing full cache line per bucket does not seem useful, especially now that we have contention on free_entries_lock for allocations and freeing of entries. Better use the space to fit more buckets.
