Subject: [PATCH net-next 0/4] net: block BH in TCP callbacks

Four layers using TCP stack were assuming sk_callback_lock could
be locked using read_lock() in their handlers because TCP stack
was running with BH disabled.

This is no longer the case. Since presumably the rest could
also depend on BH being disabled, just use read_lock_bh().

Then each layer might consider switching to RCU protection
and no longer depend on BH.

Eric Dumazet (4):
  scsi_tcp: block BH in TCP callbacks
  ocfs2/cluster: block BH in TCP callbacks
  rds: tcp: block BH in TCP callbacks
  tipc: block BH in TCP callbacks
