Hello, While reviewing the new filesystem encryption code, I was confused by the intended set of legal characters in the printable form of an encrypted filename. According to the actual code in fs/crypto/fname.c, the legal characters are: a-zA-Z0-9+, Alternatively, according to the comment in the same file, the legal characters are actually: a-zA-Z0-9+_ Still alternatively, according to the design document[1], the legal characters are actually: a-zA-Z0-9+= Which one is correct?
