But actually s_err_report isn't initialized yet and the kernel oops. The detailed information can be found https://bugzilla.kernel.org/show_bug.cgi?id=32082. The best way is to check whether the timer s_err_report is initialized or not. But it seems that in include/linux/timer.h, we can't find a good function to check the status of this timer, so this patch just move the initializtion of s_err_report earlier so that we can avoid the kernel panic. The corresponding del_timer is also added in the error path. Reported-by: Sami Liedes Signed-off-by: Tao Ma Signed-off-by: "Theodore Ts'o" --- Reading git-diff-tree failed
