Hi,
Initially, what we planned with Kees is to firstly replace all calls with
error handling codes (like this series does),
and then replace all other simple calls (without error handling). However,
we can also start a discussion about this topic, all suggestions are
welcome.
I am not sure that it does make sense to check all returns code in all
cases (for example in arch/alpha/kernel/setup.c, there are a ton of other
examples in the kernel). But a general review (as you suggest), would make
sense.
Regards,
Romain
