参数：

类型参数名称
unsigned intcaller_id
intfacility
intlevel
enum log_flagsflags
const char *text
size_tlen
1845  如果length == 0 means unused buffer 加len大于buf的长度则
1846  cont_flush()
1847  返回:false
1850  如果非length == 0 means unused buffer 则
1851  log facility of first message 等于facility
1852  log level of first message 等于level
1853  printk_caller_id() of first print 等于caller_id
1854  ime of first print 等于local_clock()
1855  prefix, newline flags 等于flags
1858  内存复制(buf + length == 0 means unused buffer , text, len)
1859  length == 0 means unused buffer 加等于len
1863  如果flags按位与xt ended with a newline 则
1864  prefix, newline flags 或等于xt ended with a newline
1865  cont_flush()
1868  返回:true
