[PATCH 09/13] fscrypto: make fname_encrypt() actually return length of ciphertext

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This makes the return value match the comment.  Previously it would
actually return 0 if encryption was successful.  (No callers currently
care.)
