[Corcodel Marian <corcodel.marian@gmail.com>]

Source: linux
Severity: normal

Hi the task_structure is defined on :
ksoftirqd file kernel/softirq.c
current file arch/x86/include/asm/current.h
curr->rq on rq structure and others

When you need to ensure as task is running need to read alls these variable and
is fortune if task is running , fortune when this  variables is actualised
correct, on conclusion bib, big mistake.
