Unfortunately, like all good documentation, it's already slightly out of date. Just this morning I noticed that as of the 2.4.2-preX, the __make_request function no longer contains this code: if (!q->plugged) q->request_fn(q); I don't know why the change was made, and I have not yet found where how q->request_fn gets called for non-plugged request queues, but since this is one of the key steps of the whole process, it will be great to keep this documentation current. robert On Wed, Feb 21, 2001 at 11:23:51PM +0100, Andries.Brouwer@cwi.nl wrote: > For a beginner I recently wrote a tiny demonstration > of what the kernel does, given a trivial user program. > Now that it served its purpose it would be a pity to > throw it out again, maybe it can be useful to someone else. > > See > http://www.win.tue.nl/~aeb/linux/vfs/trail-1.html > > Andries > > - > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/
