This commit adds a new kernel selftest to verify RTNLGRP_IPV4_MCADDR
and RTNLGRP_IPV6_MCADDR notifications. The test works by adding and
removing a dummy interface and then confirming that the system
correctly receives join and removal notifications for the 224.0.0.1
and ff02::1 multicast addresses
Thanks for the suggestion.

Currently gup_longterm assumes that filesystems support fallocate() and uses
that to allocate space in files, however this is an optional feature and is
in particular not implemented by NFSv3 which is commonly used in CI systems

Extract the network device and namespace cleanup logic from the

Rename netpoll_parse_options() to netconsole_parser_cmdline() and

Add a call to dev_dstats_rx_dropped_add() in nsim_queue_free() to
account for the number of packets dropped when purging the skb queue.
This improves the accuracy of RX drop statistics reported by

Introduce the dev_dstats_rx_dropped_add() helper to allow incrementing
the rx_drops per-CPU statistic by an arbitrary value, rather than just
one. This is useful for drivers or code paths that need to account for
multiple dropped packets at once, such as when dropping entire queues.

When the RX side of netdevsim was added, the RX statistics were missing,

This patch adds proper statistics tracking on RX side, complementing the
