Re: [Yaffs] When yaffs perform GC?

Hi,

I saw those code:

if (!dev->is_checkpointed) {
urgency = yaffs_bg_gc_urgency(dev);
gc_result = yaffs_bg_gc(dev, urgency);
if (urgency > 1)
next_gc = now + HZ / 20 + 1;
else if (urgency > 0)
next_gc = now + HZ / 10 + 1;
else
next_gc = now + HZ * 2;
}

Does it means yaffs will perform gc at least HZ*2? I mean nomorlly the HZ is around 1sec, does the gc frequence too often? Thank you.
