**untested** The TIF_XXX flags are stored in the flags field in the thread_info struct (TI_FLAGS), not in the flags field of the task_struct structure (TASK_FLAGS). It seems this bug has been in the kernel for 12 years (since v2.6.32). Signed-off-by: Helge Deller <deller@gmx.de> Fixes: ecd3d4bc06e48 ("parisc: stop using task->ptrace for {single,block}step flags")
