From cb6c18b5a41622c7a439508f7421f8766a91cb87 Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Sat, 1 Oct 2022 11:37:05 +0530 Subject: [PATCH] perf/mem: Rename PERF_MEM_LVLNUM_EXTN_MEM to PERF_MEM_LVLNUM_CXL PERF_MEM_LVLNUM_EXTN_MEM was introduced to cover CXL devices but it's bit ambiguous name and also not generic enough to cover cxl.cache and cxl.io devices. Rename it to PERF_MEM_LVLNUM_CXL to be more specific.
