Message-Id: <1348082576-10528-3-git-send-email-dmonakhov@openvz.org> Date: Wed, 19 Sep 2012 23:22:54 +0400 From: Dmitry Monakhov <dmonakhov@...nvz.org> To: linux-ext4@...r.kernel.org, fio@...r.kernel.org Cc: axboe@...nel.dk, Dmitry Monakhov <dmonakhov@...nvz.org> Subject: [PATCH 2/4] ioengine: allow several external ioengines Currently only one external ioengine can be exported because it use hardcoded 'ioengine' symbol, but if we allow external modules to have ops symbol similar to it's name then several extrnal engines become possible.
