R. Silva" <gustavoars@...nel.org> Subject: [GIT PULL] Enable -Wimplicit-fallthrough for Clang for 5.16-rc1 The following changes since commit 3906fe9bb7f1a2c8667ae54e967dc8690824f4ea: Linux 5.15-rc7 (2021-10-25 11:30:31 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git tags/enable-clang-fallthrough-5.16-rc1 for you to fetch changes up to 428a8bf629ecc118d1eadbb629312c25fde2103f: Makefile: Enable -Wimplicit-fallthrough for Clang (2021-11-13 15:24:33 -0600) ---------------------------------------------------------------- Enable -Wimplicit-fallthrough for Clang for 5.16-rc1 Hi Linus, Please, pull the following patch that enables -Wimplicit-fallthrough for Clang 14+, globally. We had almost 40,000[1] of these issues for Clang in the beginning, and now I think we are in good shape and it is now possible to enable -Wimplicit-fallthrough for Clang, with this finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) I have to say that I'm sending this pull-request this late in the merge window, intentionally. I first wated to make sure that no other warning shows up before sending it. This patch has been baking in linux-next for a couple of developement cycles, now. So, I think we are pretty much ready to merge it into mainline. [1] https://github.com/KSPP/linux/issues/115 Thanks! ---------------------------------------------------------------- Gustavo A. R.
