[PATCH] eligible_child: remove an obsolete ->tgid check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


It is not possible to find a sub-thread in ->children/->ptrace_children
lists, ptrace_attach() does not allow to attach to sub-threads.

Even if it was possible to ptrace the task from the same thread group,
we can't allow to release ->group_leader while there are others (ptracer)
threads in the same group.
