From 773d9e2d8dbf02cfaf65786cf9100eef02c9fda4 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 3 Mar 2010 11:47:42 -0700 Subject: ioat3: cleanup, don't enable DCA completion writes We already disallow raid operations while DCA is globally enabled, so having it locally enabled is a nop and confusing when reading the code.
