From a48bd961fb203a7ce68f8110fc53a85f90e24b33 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 2 Jun 2026 18:41:50 -0700 Subject: [PATCH] kbuild: Remove unnecessary 'T' modifier in cmd_ar_builtin_fixup In cmd_ar_builtin_fixup, the 'T' modifier was added to '$(AR) mPi' to work around a bug in llvm-ar that caused thin archives to be silently converted to full archives [1]. Since commit 20c098928356 ("kbuild: Bump minimum version of LLVM for building the kernel to 15.0.0"), all supported versions of llvm-ar have this issue fixed, so the 'T' modifier and comment can be removed.
