From 4f73462856576797b8f3c55564a9be99f76dc67b Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 31 Aug 2026 18:46:31 -0700 Subject: [PATCH] scripts/sorttable: Mark long_size as __maybe_unused When building in a kernel tree prior to commit b055f4c431e3 ("sorttable: Move ELF parsing into scripts/elf-parse.[ch]") with clang-23 or newer, which implements a new warning under -Wunused-but-set-variable for static global variable, there is a warning from sorttable because long_size is unused when MCOUNT_SORT_ENABLED is not set: scripts/sorttable.c:452:12: error: variable 'long_size' set but not used [-Werror,-Wunused-but-set-global] 452 | static int long_size; | ^ Mark long_size as __maybe_unused to avoid inserting more ugly #ifdef directives while insuring the warning does not reappear, as the aforementioned change does not alter the uses of long_size, so it appears to be coincidence that the warning disappears after this refactoring.
