函数名称：moyo_fill_path_info - Fill in "struct tomoyo_path_info" members.*@ptr: Pointer to "struct tomoyo_path_info" to fill in.* The caller sets "struct tomoyo_path_info"->name.

函数原型：void tomoyo_fill_path_info(struct tomoyo_path_info *ptr)

返回类型：void

参数：

类型参数名称
struct tomoyo_path_info *ptr
657  name等于name
658  len等于strlen - Find the length of a string*@s: The string to be sized
660  = tomoyo_const_part_length(name) 等于moyo_const_part_length - Evaluate the initial length without a pattern in a token.*@filename: The string to evaluate.* Returns the initial length without a pattern in @filename.
661  = tomoyo_strendswith(name, "/") 等于len且name[len - 1]恒等于'/'
662  = tomoyo_path_contains_pattern(name) 等于 = tomoyo_const_part_length(name) 小于len
663  = full_name_hash(name, strlen(name)) 等于Version 2: One word (32 or 64 bits) at a time.* If CONFIG_DCACHE_WORD_ACCESS is defined (meaning * exists, which describes major Linux platforms like x86 and ARM), then* this computes a different hash function much faster.
