Subject: [PATCH] x86/sgx: Drop 'page_index' from sgx_backing
Date: Fri, 8 Jul 2022 09:21:24 -0700 [thread overview]
Message-ID: <20220708162124.8442-1-kristen@linux.intel.com> (raw)
From: Sean Christopherson <sean.j.christopherson@intel.com>
Storing the 'page_index' value in the sgx_backing struct is
dead code and no longer needed.
