San In Japaneese as per wiki....

-
The English titles of "Mr", "Mrs", "Miss", "Ms" are all irrelevant as all people are referred to by the suffix -san (さん?). The more polite -sama (様?) suffix is used only in certain contexts with people who are superior in social standing to you, and is also gender-neutral in usage. The most polite suffix -dono (殿?) usually, but not always, refers to males, and is rarely used in modern speech. Both -sama (様?) and -dono (殿?) should be used with caution, and only with more than basic understanding of Japanese social structures.

Tracking Linux kworker threads

-
How to find out which part of kernel/module has created this workqueue. How to track a kworker-thread named for example ''kworker/0:3 to its origin in kernel-space? I found  this thread on lkml  that answers your question a little. (It seems even Linus himself was puzzled as to how to find out the origin of those threads.) Basically, there are two ways of doing this: $ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event $ cat /sys/kernel/debug/tracing/trace_pipe > out.txt (wait a few secs) For this you will need  ftrace  to be compiled in your kernel, and to enable it with: mount -t debugfs nodev /sys/kernel/debug More information on the function tracer facilities of Linux is available in the  ftrace.txt documentation . This will output what threads are all doing, and is useful for tracing multiple small jobs. cat /proc/THE_OFFENDING_KWORKER/stack This will output the stack of a single thread doing a lot of work. ...

Copy_to_user or copy_from_user instead of memcpy

-
Quite the contrary, it does handle the case for swapped out memory. Lets take a look at it, shall we? copy_to/from_user boils down to __copy_user in arch/i386/lib/usercopy.c: #define __copy_user(to,from,size) \ do { \ int __d0, __d1, __d2; \ __asm__ __volatile__( \ " cmp $7,%0\n" \ " jbe 1f\n" \ " movl %1,%0\n" \ " negl %0\n" \ " andl $7,%0\n" \ " subl %0,%3\n" \ "4: rep; movsb\n" \ " movl %3,%0\n" ...
