From 0abea0b7428f930d423640feb4472218b83b8eea Mon Sep 17 00:00:00 2001 From: Dmitry Monakhov Date: Wed, 19 Sep 2012 23:22:54 +0400 Subject: [PATCH] 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.
