This member is redundant and its presence does not benefit multi-instance setups, as reported by Jay Vosburgh. Eliminating it cleans up the structure and removes unnecessary code. The second patch updates the netpoll resource cleanup routine to use synchronize_net() instead of synchronize_rcu(). As __netpoll_free() is always called under the RTNL lock, using synchronize_net() leverages the more efficient synchronize_rcu_expedited() in these contexts, reducing time spent in critical sections and improving performance. Both changes simplify maintenance and enhance efficiency without altering netpoll behavior. ==================== Link: https://patch.msgid.link/20250918-netpoll_jv-v1-0-67d50eeb2c26@debian.org Signed-off-by: Jakub Kicinski --- 312e6f7676e63bbb9b81e5c68e580a9f776cc6f0
