Subject: [PATCH v1 01/13] KVM: s390: wrapper for KVM_BUG
Date: Wed,  8 Jan 2025 19:14:39 +0100	[thread overview]
Message-ID: <20250108181451.74383-2-imbrenda@linux.ibm.com> (raw)
In-Reply-To: <20250108181451.74383-1-imbrenda@linux.ibm.com>

Wrap the call to KVM_BUG; this reduces code duplication and improves
readability.
