Quoting Eric W. Biederman (ebiederm at xmission.com): > To avoid pid rollover confusion the kernel needs to work with > struct pid * instead of pid_t. Currently there is not an iterator > that walks through all of the tasks of a given pid type starting > with a struct pid. This prevents us replacing some pid_t instances > with struct pid. So this patch adds do_each_pid_task which walks > through the set of task for a given pid type starting with a struct pid. > > Signed-off-by: Eric W.
