The allocation backtrace is: orphan pointer 0xf548fde0 (size 76): c0174674: c01591ee: <__delayacct_tsk_init> c0127e06: c0128cd2: c0104d39: I'm not sure whether the leak occurs but there might be a path where task_struct is freed and the task->delays pointer is lost. Could you please have a look at this?
