From 3ca12ee976e44a1126775a8e801889d42dd06980 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Sat, 17 Oct 2015 21:51:45 +0100 Subject: [PATCH] pipe-loader: dlopen/dlsym the pipe-driver at probe time Rather than giving false hopes that things might work, just check at probe time. This allows us to remove the duplication and consolidate the code wrt the upcomming static pipe-loader.
