Similar to the notifier_call callback of a notifier_block, change the

The FDB dump callback requires the related net_device so move it to the

The net_device associated to a dump operation does not have to be passed
to the callback. switchdev stores it in a superset struct, if needed.
Also some drivers (such as DSA drivers) may not have easy access to it.
This will simplify pushing the callback function down to the drivers.

that opens a file descriptor for an event source.
Based on our initial experience aiming to use the core perf
infrastructure, this interface is inspired by perf, but focused on
exposing metrics about work running on Gen graph
After some recent progress enabling the Observation Architecture unit
for Gen8+, we can hopefully paint a fairly complete picture of the

I'm looking again at the challenges in upstreaming this work.
Considering this, it looked lik

The fatal_signal_pending() was added to suppress unnecessary "sharing
same memory" message, but it can't 100% help anyway because it can be
false-negative; SIGKILL can be already dequeued.
And worse, it can be false-positive due to exec or coredump. exec is

in particular that "kill sharing same memory" loop can miss a process
with a zombie leader which uses the same ->mm.
Note: the process_has_mm(child, p->mm) ch
