From 8afaefb8919dc8746a57c450a758717c516c7b0a Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 30 Jul 2013 14:58:27 +0200 Subject: block: Disable driver-specific options for 1.6 We don't want to commit to the API yet before everything is worked out. Like already for 1.5, disable it again for the 1.6 release. This commit is meant to be reverted after the 1.6 release. The disabling of the driver-specific options is achieved by applying the old checks while parsing the command line.
