Subject: [PATCH 14/19] KVM: x86/emulate: Remove unused "ctxt" of setup_syscalls_segments()
Date: Tue, 25 Jan 2022 17:59:04 +0800 [thread overview]
Message-ID: <20220125095909.38122-15-cloudliang@tencent.com> (raw)
In-Reply-To: <20220125095909.38122-1-cloudliang@tencent.com>
From: Jinrong Liang <cloudliang@tencent.com>
The "struct x86_emulate_ctxt *ctxt" parameter of setup_syscalls_segments()
is not used, so remove it. No functional change intended.
