Yep. Thanks, Stephen.

Linus:

After you have merged all the trees containing fall-through patches, you might
see the following warnings:

arch/x86/events/intel/core.c:4957:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
arch/x86/events/intel/core.c:5006:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/mtd/nand/onenand/onenand_base.c:3261:6: warning: this statement may fall through [-Wimplicit-fallthrough=]

for which I already have patches ready to be applied, but I didn't include them
in my pull-request because such patches don't apply to 5.2-rc2, on which I based
my -next tree for v5.3.

We can coordinate and I can send you the patches that address those and any other
warning that you might see after merging my pull-request and just before you release
5.3-rc1. So we can have the -Wimplicit-fallthrough option globally enabled in
5.3-rc1 and zero fall-through warnings.

What do you think?

Thanks
