Sorry to repeat .. I didn't see this go out on the list and I haven't
had any reply. So let's ask again. Is this a new coding error in ll_rw_blk?
-----------------
The following has been lost from __make_request() in ll_rw_blk.c since
2.4.2 (incl):
out:
- if (!q->plugged)
- (q->request_fn)(q);
if (freereq)
The result is that a block device that doesn't do plugging doesn't
work.
If it has called blk_queue_pluggable() to register a no-op plug_fn,
then q->plugged will never be set (it's the duty of the plug_fn), and
the devices registered request function will never be called.
This behaviour is distinct from 2.4.0, where registering a no-op
plug_fn made things work fine.
Is this a coding oversight?
