I've run bloat-o-meter on the vmlinux.o file now and indeed it shows
what is going on: the configuration that triggered this has
CONFIG_PROFILE_ANNOTATED_BRANCHES, which turns the unlikely()
bit in IS_ERR() into two extra function calls, so my patch does
end up adding a bit of bloat (see output below):
text data bss dec hex filename
20159943 5630468 16199728 41990139 280b7fb build/s390/0xCED6EE04_defconfig/vmlinux-old.o
20217607 5630404 16199728 42047739 28198fb build/s390/0xCED6EE04_defconfig/vmlinux-new.o
Without CONFIG_PROFILE_ANNOTATED_BRANCHES, the changes are
very small, with around 100 functions growing or shrinking
by a few bytes.
I don't think we care much about the size increase when that
option is enabled, but I do wonder what behavior makes more
sense regarding the annotation for every single IS_ERR().
Does it make sense to have every instance get its own counter,
or would it make sense to actually try to reduce these
when profiling the annotations?
