Allowing Unprotected Reads

NOTE(DATA_READABLE_WITHOUT_LOCK(DataNameList))

This annotation is allowed both outside and inside a function definition. It informs LockLint that the specified data may be read without holding the protecting locks. This is useful with an atomically readable datum that stands alone (as opposed to a set of data whose values are used together), since it is valid to peek at the unprotected data if you do not intend to modify it.
