From e48b92f9e140ff632ad426c0a94e3630a61e45d8 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 19 May 2025 11:51:16 -0300 Subject: [PATCH] tools headers: Synchronize linux/bits.h with the kernel sources To pick up the changes in this cset: 0312e94abe484b9e ("treewide: fix typo 'unsigned __init128' -> 'unsigned __int128'") This addresses these perf build warnings: Warning: Kernel ABI header differences: diff -u tools/include/linux/bits.h include/linux/bits.h This required picking the const_true() define in linux/compiler.h as a prep patch as that macro is used in the new linux/bits.h Please see tools/include/uapi/README for further details.
