6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eduard Zingerman eddyz87@gmail.com
commit 3c4e420cb6536026ddd50eaaff5f30e4f144200d upstream.
Subsequent patches would make use of explored_state() function. Move it up to avoid adding unnecessary prototype.
