This patch series provide a new mmap_hook to fs willing to grab
a mutex before mm->mmap_sem is taken, to ensure lockdep sanity.
This hook allows us to shorten tcp_mmap() execution time (while mmap_sem
is held), and improve multi-threading scalability.
Eric Dumazet (4):
mm: provide a mmap_hook infrastructure
net: implement sock_mmap_hook()
tcp: provide tcp_mmap_hook()
tcp: mmap: move the skb cleanup to tcp_mmap_hook()
