From dee28e72b619b48ec80a9e5509db458dbe66f71f Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Thu, 21 Jul 2011 16:57:55 -0400 Subject: pstore: Allow the user to explicitly choose a backend pstore only allows one backend to be registered at present, but the system may provide several. Add a parameter to allow the user to choose which backend will be used rather than just relying on load order.
