I've been getting these for years too! Well, I've had these in local
policy for several releases:

# Samba needs to be able to access stuff under /srv
allow smbd_t var_t:dir getattr;

# F11 noise reduction
dontaudit smbd_t lost_found_t:dir { getattr read };
dontaudit smbd_t squid_cache_t:dir getattr;
dontaudit smbd_t mysqld_db_t:dir getattr;
