Subject: [PATCH v5 2/5] [Trivial]KVM: x86: Explicitly cast ulong to bool in kvm_set_cr3()
Date: Mon, 27 Feb 2023 16:45:44 +0800 [thread overview]
Message-ID: <20230227084547.404871-3-robert.hu@linux.intel.com> (raw)
In-Reply-To: <20230227084547.404871-1-robert.hu@linux.intel.com>
kvm_read_cr4_bits() returns ulong, explicitly cast it bool when assign to a
bool variable.
