393  BUILD_BUG_ON - break compile if a condition is true(ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(TAINT_FORCED_RMMOD could be a per-module flag but the module* is being removed anyway.) != TAINT_FLAGS_COUNT)
395  如果tainted_mask则
399  s等于buf加输出格式化串
400  以i小于TAINT_FLAGS_COUNT循环
401  t等于TAINT_FORCED_RMMOD could be a per-module flag but the module* is being removed anyway.[i]
402  s自加等于如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则 character printed when tainted 否则 character printed when not tainted
405  s等于0
406  否则snprintf - Format a string and place it in a buffer*@buf: The buffer to place the result into*@size: The size of the buffer, including the trailing null space*@fmt: The format string to use*@
