Subject: [PATCH net 0/2] __napi_schedule_irqoff() used in wrong context
Date: Tue, 26 Nov 2019 23:20:11 +0100 [thread overview]
Message-ID: <20191126222013.1904785-1-bigeasy@linutronix.de> (raw)
I found three cases where __napi_schedule_irqoff() could be used with
enabled interrupts while looking for something else… There are patches
for two of them.
The third one, hyperv/netvsc, is wrong with the `threadirqs' commandline
option because the interrupt will be delivered directly via the vector
and not the thread. I will try to sort this out with the x86 folks.
Sebastian
