Opening a file in kernel mode is not recommended, for security and design philosophy reason. Even purely for debug tracing, it is not good, because opening a file is too much disturbance to the real work kernel is doing so may not get the accurate debugging information. printk() does a good work because it merely stores the message in a in-memory buffer (much cheaper than writing to a file directly), and user-space Ksyslog will copy the content of the buffer to log files. > also which time function should be used to get the current time in the logs. > > -- > Thank You, > Siddhesh M.
