Hi Linus, Please pull these changes to clean up the new GCC 9 warnings coming from -Wmissing-attributes. With this, we can avoid disabling them.
The patches have been for quite in -next in several forms/shapes during the iterations we did. Cheers, Miguel The following changes since commit 8834f5600cf3c8db365e18a3d5cac2c2780c81e5: Linux 5.0-rc5 (2019-02-03 13:48:04 -0800) are available in the Git repository at: https://github.com/ojeda/linux.git tags/compiler-attributes-for-linus-v5.0-rc7 for you to fetch changes up to a6e60d84989fa0e91db7f236eda40453b0e44afa: include/linux/module.h: copy __init/__exit attrs to init/cleanup_module (2019-02-15 19:52:56 +0100) ---------------------------------------------------------------- Compiler Attributes: Clean the new GCC 9 -Wmissing-attributes warnings The upcoming GCC 9 release extends the -Wmissing-attributes warnings (enabled by -Wall) to C and aliases: it warns when particular function attributes are missing in the aliases but not in their target, e.g.: void __cold f(void) {} void __alias("f") g(void); diagnoses: warning: 'g' specifies less restrictive attribute than its target 'f': 'cold' [-Wmissing-attributes] These patch series clean these new warnings. Most of them are caused by the module_init/exit macros.
