Subject: Possible memory leak in kernel/delayacct.c
Date: Sat, 19 Aug 2006 11:58:41 +0100 [thread overview]
Message-ID: <b0943d9e0608190358i7cb93b75g1b52d2f1b7e6f1a@mail.gmail.com> (raw)
Hi Shailabh,
Michal was running some kmemleak tests and there are about 20 orphan
pointers reported in delayacct.c. The allocation backtrace is:
orphan pointer 0xf548fde0 (size 76):
c0174674: <kmem_cache_zalloc>
c01591ee: <__delayacct_tsk_init>
c0127e06: <copy_process>
c0128cd2: <do_fork>
c0104d39: <sys_clone>
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? Thanks.
