cleandisk

cleandisk 时没有考虑到并行，可以用 barrier
cleancache 也是

I ran this through google translate, but I am not sure what you are trying to say. I hope one day to learn Mandarin 😄.

sorry,i thought you are chinese, sorry
i remind that method "cleanDisk()" should run under
dispatch_barrier_async(<#queue: dispatch_queue_t#>, <#block: dispatch_block_t##() -> Void#>).
because maybe crash in concurrence，when i call cleanDisk() and call fromDisk(...) immediately

All good. I think I understand now, probably be a smart addition to protect against race conditions.
