From: Colin Ian King <[email protected]> The mutexes swap_slots_cache_mutex and swap_slots_cache_enable_mutex are local to the source and do not need to be in global scope, so make them static.
Cleans up sparse warnings: symbol 'swap_slots_cache_mutex' was not declared. Should it be static? symbol 'swap_slots_cache_enable_mutex' was not declared. Should it be static?
