UBSAN has been somehow useful to pick some problems, so, I try to invest
some time understand
Hello,
I am seeing some signed-integer-overflow in percpu reference counters.
UBSAN: signed-integer-overflow in
./arch/arm64/include/asm/atomic_lse.h:204:1
-9223372036854775808 - 1 cannot be represented in type 's64' (aka 'long
long')
Call trace:
handle_overflo
loc_netdev_mqs14811450 -31
On x86_64 with several NICs of different vendors, I was never able to
get a &net_device pointer not aligned to the cacheline size after the
change.

On x86_64 with several NICs of different vendors, I was never able to
get a &net_device pointer not aligned to the cacheline size after the
