THREADGROUP_CHANGE_B(9)                   Driver Basics                   THREADGROUP_CHANGE_B(9)



NAME
       threadgroup_change_begin - mark the beginning of changes to a threadgroup

SYNOPSIS
       void threadgroup_change_begin(struct task_struct * tsk);

ARGUMENTS
       tsk
           task causing the changes

DESCRIPTION
       All operations which modify a threadgroup - a new thread joining the group, death of a
       member thread (the assertion of PF_EXITING) and exec(2) dethreading the process and
       replacing the leader - are wrapped by threadgroup_change_{begin|end}(). This is to provide
       a place which subsystems needing threadgroup stability can hook into for synchronization.
