ipv4: Fix oops with FIB_TRIE
It seems we can fix this by disabling preemption while we re-balance the trie. This is with the CONFIG_CLASSIC_RCU. It's been stress-tested at high loads continuesly taking a full BGP table up/down via iproute -batch. Note. fib_trie is not updated for CONFIG_PREEMPT_RCU Reported-by: Andrei Popa Signed-off-by: Robert Olsson <robert.olsson@its.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net>
