Subject: PREEMPT_RT vs bcache
Date: Wed, 07 Aug 2013 22:28:18 +0200 [thread overview]

As Kent said back in 2011 (commit 84759c6d18c5), bcache needs
{down,up}_read_non_owner(). But these are not implemented by the -rt
patchset when PREEMPT_RT_FULL is enabled. Can they be added, or is
there a fundamental conflict here?
Ben.
