The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=a852dc580c1c261bc50fd9788b52abca0004661b commit a852dc580c1c261bc50fd9788b52abca0004661b Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2024-08-28 18:57:43 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2024-08-28 19:12:32 +0000 vmm: Harmonize compat ioctl definitions For compat ioctls and structures, we use a mix of suffixes: _old, _fbsd<version>, _<version>. Standardize on _<version> to make things more consistent. No functional change intended.
