[ Upstream commit 08062af0a52107a243f7608fd972edb54ca5b7f8 ]
In commit 6f8b12d661d0 ("net: napi: add hard irqs deferral feature") napi_defer_irqs was added to net_device and napi_defer_irqs_count was added to napi_struct, both as type int.
This value never goes below zero, so there is not reason for it to be a signed int. Change the type for both from int to u32, and add an overflow check to sysfs to limit the value to S32_MAX.
Could you explain why you want to backport this change to stable?
