Chunguang Wu 522dc4e5f5 fs/proc: add Kthread flag to /proc/$pid/status 
The command `ps -ef ` and `top -c` mark kernel thread by '[' and ']', but
sometimes the result is not correct.  The task->flags in /proc/$pid/stat
is good, but we need remember the value of PF_KTHREAD is 0x00200000 and
convert dec to hex.  If we have no binary program and shell script which
read /proc/$pid/stat, we can know it directly by `cat /proc/$pid/status`.
