Subject: [PATCH 0/2] media: Use complete() instead complete_all()
Date: Fri, 16 Sep 2016 13:18:20 +0200 [thread overview]
Message-ID: <1474024702-19436-1-git-send-email-wagi@monom.org> (raw)
From: Daniel Wagner <daniel.wagner@bmw-carit.de>
Hi,
Using complete_all() is not wrong per se but it suggest that there
might be more than one waiter. 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.
cheers,
daniel
