It utilize custom hook of jemalloc arena, and when jemalloc arena request memory from system, the allocator use the hook to set `MADV_DONTDUMP ` to the memory. The implementation is basically the same as `folly::JemallocNodumpAllocator`, except for some minor difference:\n1. It only support jemalloc >= 5.0\n2. When the allocator destruct, it explicitly destruct the corresponding arena via `arena.<i>.destroy` via `mallctl`.\n\nDepending on #4502.\nPull Request resolved: https://github.com/facebook/rocksdb/pull/4534\n\nDifferential Revision: D10435474\n\nPulled By: yiwu-arbug\n\nfbshipit-source-id: e80edea755d3853182485d2be710376384ce0bb4","distinct":true,"url":"https://api.github.com/repos/riversand963/rocksdb/commits/5f5fddabc78d18d71eb711db12421fdfff866665"}]}
