Subject: [PATCH 5.15.y v2 1/8] KVM: x86/mmu: Use a bool for direct
Date: Fri, 26 Jun 2026 19:46:12 +0200	[thread overview]
Message-ID: <20260626174620.1819772-2-pbonzini@redhat.com> (raw)
In-Reply-To: <20260626174620.1819772-1-pbonzini@redhat.com>

From: David Matlack <dmatlack@google.com>

commit 27a59d57f073f21f029df1517c2c0a1abea5b0ce upstream.

The parameter "direct" can either be true or false, and all of the
callers pass in a bool variable or true/false literal, so just use the
type bool.

No functional change intended.
