REPARENT_TO_KTHREADD(9) Driver Basics REPARENT_TO_KTHREADD(9)
NAME
reparent_to_kthreadd - Reparent the calling kernel thread to kthreadd
SYNOPSIS
void reparent_to_kthreadd(void);
ARGUMENTS
void
no arguments
DESCRIPTION
If a kernel thread is launched as a result of a system call, or if it ever exits, it should generally reparent itself to kthreadd so it
isn't in the way of other processes and is correctly cleaned up on exit.
The various task state such as scheduling policy and priority may have been inherited from a user process, so we reset them to sane values
here.
NOTE that reparent_to_kthreadd gives the caller full capabilities.
