| |
My system's nr_tasks (as shown in /proc/loadavg) was growing with time, while the number of processes (as seen in ps -aux) remained basically constant.
In kernel/exit.c, it apears that nr_tasks decrement isn't protected by any locks. I moved all modifying of nr_tasks into <add|get>_free_taskslot() in include/linux/sched.h. Here it is protected by the taskslot_lock. The problem looks fixed.
This is the first real playing I've done in the kernel, so I'd really apreciate some feedback from someone with more of a clue.
