[Qemu-devel] [PATCH v2] blockdev: Print a warning for legacy drive options that belong to -device |
Date: |
Fri, 12 May 2017 12:33:49 +0200 |
We likely do not want to carry these legacy -drive options along forever.
Let's emit a deprecation warning for the -drive options that have a
replacement with the -device option, so that the (hopefully few) remaining
users are aware of this and can adapt their scripts / behaviour accordingly.

v2:
- Check for !qtest_enabled() since tests/hd-geo-test still uses these
- Added "addr" to the list, too
- Also mark the options as deprecated in the documentation
