494  如果prefix则
495  hname等于aa_str_alloc(strlen - Find the length of a string*@s: The string to be sized + strlen - Find the length of a string*@s: The string to be sized + 3, gfp)
496  如果hname则输出格式化串
498  否则
499  hname等于aa_str_alloc(strlen - Find the length of a string*@s: The string to be sized + 1, gfp)
500  如果hname则strcpy(hname, name)
503  如果非hname则返回:false
505  hname等于hname
507  name等于asename - find the last component of an hname*@name: hname to find the base profile name component of (NOT NULL)* Returns: the tail (base profile name) name component of an hname
