Subject: [RFC PATCH 07/31] KVM: selftests: Fix ghcb_entry returned in ghcb_alloc()
Date: Fri, 28 Feb 2025 15:00:00 +0530	[thread overview]
Message-ID: <20250228093024.114983-8-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250228093024.114983-1-Neeraj.Upadhyay@amd.com>

Currently, ghcb_alloc() always returns first entry. Fix
it to return an unused entry.
