2019-10-12 17:04:44.008 ffff94f3b010 4 rocksdb: Fast CRC32 supported: Not support on x86

Checking source code: https://github.com/ceph/rocksdb/blob/37828c548a886dccf58a7a93fc2ce13877884c0c/util/crc32c.cc
the Func IsFastCrc32Supported hasn't supported AArch64 platform.

The newest rocksdb source branch has added Fast CRC32 supported on AArch64.
