Merge tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux
Pull 'fallthrough' keyword conversion from Gustavo A. R. Silva: "A tree-wide patch that replaces tons (2484) of /* fall through */ comments, and its variants, with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case. There are currently 1167 intances of this fallthrough pseudo-keyword macro in mainline (5.9-rc2), that have been introduced over the last couple of development cycles: $ git grep -nw 'fallthrough;' | wc -l 1167 The global adoption of the fallthrough pseudo-keyword is something certain to happen; so, better sooner than later. :) This will also save everybody's time and thousands of lines of unnecessarily repetitive changelog text. After applying this patch on top of 5.9-rc2, we'll have a total of 3651 instances of this macro: $ git grep -nw 'fallthrough;' | wc -l 3651 This treewide patch doesn't address ALL fall-through markings in all subsystems at once because I have previously sent out patches for some of such subsystems separately, and I will follow up on them; however, this definitely contributes most of the work needed to replace all the fall-through markings with the fallthrough pseudo-keyword macro in the whole codebase. I have build-tested this patch on 10 different architectures: x86_64, i386, arm64, powerpc, s390, sparc64, sh, m68k, powerpc64 and alpha (allyesconfig for all of them). This is in linux-next already and kernel test robot has also helped me to successfully build-test early versions of this patch[2][3][4][5]" [1] https://www.kernel.org/doc/html/v5.7/process/deprecated.html?highlight=fallthrough#implicit-switch-case-fall-through [2] https://lore.kernel.org/lkml/5f3cc99a.HgvOW3rH0mD0RmkM%25lkp@intel.com/ [3] https://lore.kernel.org/lkml/5f3dd1d2.l1axczH+t4hMBZ63%25lkp@intel.com/ [4] https://lore.kernel.org/lkml/5f3e977a.mwYHUIObbR4SHr0B%25lkp@intel.com/ [5] https://lore.kernel.org/lkml/5f3f9e1c.qsyb%2FaySkiXNpkO4%25lkp@intel.com/ * tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: treewide: Use fallthrough pseudo-keyword
