Re: [PATCH net-next v2 2/3] ipv4: Pass netns to fib_table_lookup()

On 10/8/26 7:31 AM, Ido Schimmel wrote:

The next patch will report the network namespace cookie in the
fib_table_lookup tracepoint. As a preparation, pass the namespace to
fib_table_lookup() and from there to the tracepoint, like the
fib6_table_lookup tracepoint. All the callers already have the namespace
at hand.

Add the namespace as the last tracepoint argument so that the positions
of the existing arguments do not change and BPF programs that attach to
the raw tracepoint are not affected.

No functional changes intended.
