Subject: [PATCH 2/3] x86/sgx: Remove unused size and count definitions
Date: Sat, 11 Jul 2026 12:00:56 +0200 [thread overview]
Message-ID: <20260711100053.739588-7-thorsten.blum@linux.dev> (raw)
In-Reply-To: <20260711100053.739588-5-thorsten.blum@linux.dev>
The definitions were added with commit 70d3b8ddcd20 ("x86/sgx: Add SGX
architectural data structures"), but have never been used. The SIGSTRUCT
reserved field sizes are also redundant because the structure uses
literal sizes instead. Remove them.
