Subject: [PATCH 0/4]  Use complete() instead of complete_all()

From: Daniel Wagner <daniel.wagner@...-carit.de>

Hi,

Using complete_all() is not wrong per se but it suggest that there
might be more than one reader. For -rt I am reviewing all
complete_all() users and would like to leave only the real ones in the
tree. The main problem for -rt about complete_all() is that it can be
uses inside IRQ context and that can lead to unbounded amount work
inside the interrupt handler. That is a no no for -rt.

The patches grouped per subsystem and in small batches to allow
reviewing. Unfortanatly I am not so good in coming up with unique
commit message, so please bear with me in that regard. I could also
squash them together, although each patch containts a very short
reasoning why there is only one waiter. Let me know what you rather
prefer. One patch which updates all complete_all() users or those 4
patches with some reasoning.

It is only test compiled because I don't have the all the hardware.

cheers,
daniel
