From 22e36ea9f5d7707ae3d64c497d172f4ef735c353 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 22 Feb 2024 10:50:17 +0000 Subject: inet: allow ip_valid_fib_dump_req() to be called with RTNL or RCU Add a new field into struct fib_dump_filter, to let callers tell if they use RTNL locking or RCU. This is used in the following patch, when inet_dump_fib() no longer holds RTNL. Signed-off-by: Eric Dumazet Reviewed-by: Donald Hunter Signed-off-by: David S.
