Subject: PREEMPT_RT vs bcache
Date: Wed, 07 Aug 2013 22:28:18 +0200	[thread overview]
Message-ID: <1375907298.27403.35.camel@deadeye.wl.decadent.org.uk> (raw)

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.
