Details are described in each commit log.\n\n\nThis patch (of 3):\n\nA use-after-free issue has been reported regarding the timer sc_timer on\nthe nilfs_sc_info structure.\n\nThe problem is that even though it is used to wake up a sleeping log\nwriter thread, sc_timer is not shut down until the nilfs_sc_info structure\nis about to be freed, and is used regardless of the thread's lifetime.\n\nFix this issue by limiting the use of sc_timer only while the log writer\nthread is alive."
