Summary: Static variables in header files will be instantiated in every file that includes the header file. This patch moves some of them from options_helper.h to its .cc files. It also moves the static variable out of the offset_of since the template function could also lead to multiple instantiation perhaps due to inlining. Fixes https://github.com/facebook/rocksdb/issues/3176 Closes https://github.com/facebook/rocksdb/pull/3178 Differential Revision: D6363794 Pulled By: maysamyabandeh fbshipit-source-id: d0a07f061b4d992ab4e0de2706e622131d258fdd
