I am wondering if the change could be one mega patch (see below) or normal patch per file about 100 patches or somewhere half way by collecting early acks. clang has a number of useful, new warnings see https://clang.llvm.org/docs/DiagnosticsReference.html This change cleans up -Wunreachable-code-break https://clang.llvm.org/docs/DiagnosticsReference.html#wunreachable-code-break for 266 of 485 warnings in this week's linux-next, allyesconfig on x86_64. The method of fixing was to look for warnings where the preceding statement was a simple statement and by inspection made the subsequent break unneeded. In order of frequency these look like return and break switch (c->x86_vendor) { case X86_VENDOR_INTEL: intel_p5_mcheck_init(c); return 1; - break; goto and break default: operation = 0; /* make gcc happy */ goto fail_response; - break; break and break case COLOR_SPACE_SRGB: /* by pass */ REG_SET(OUTPUT_CSC_CONTROL, 0, OUTPUT_CSC_GRPH_MODE, 0); break; - break; The exception to the simple statement, is a switch case with a block and the end of block is a return struct obj_buffer *buff = r->ptr; return scnprintf(str, PRIV_STR_SIZE, "size=%u\naddr=0x%X\n", buff->size, buff->addr); } - break; Not considered obvious and excluded, breaks after multi level switches complicated if-else if-else blocks panic() or similar calls And there is an odd addition of a 'fallthrough' in drivers/tty/nozomi.c Tom Acked-by: Dan Williams diff --git a/arch/x86/kernel/cpu/mce/core.c b/arch/x86/kernel/cpu/mce/core.c index 1c08cb9eb9f6..16ce86aed8e2 100644 --- a/arch/x86/kernel/cpu/mce/core.c +++ b/arch/x86/kernel/cpu/mce/core.c @@ -1809,15 +1809,13 @@ static int __mcheck_cpu_ancient_init(struct cpuinfo_x86 *c) switch (c->x86_vendor) { case X86_VENDOR_INTEL: intel_p5_mcheck_init(c);
