And thus the patch looks like another bugfix to me. Just one question, and this question is offtopic again, > Only kernel tasks can be non-freezable (PF_NOFREEZE) Hmm. We seem to "leak" PF_NOFREEZE if a kernel thread execs? Perhaps do_execve_common() should do set_freezable() before return. Or, at least, simply clear this flag along with PF_KTHREAD in flush_old_exec().
