Subject: [bpf PATCH v3 0/3] BPF, a couple sockmap fixes

While testing sockmap with more programs (besides our test programs)
I found a couple issues.

The attached series fixes an issue where pinned maps were not
working correctly, blocking sockets returned zero, and an error
path that when the sock hit an out of memory case resulted in a
double page_put() while doing ingress redirects.

See individual patches for more details.

v2: Incorporated Daniel's feedback to use map ops for uref put op
    which also fixed the build error discovered in v1.
v3: rename map_put_uref to map_release_uref

John Fastabend (3):
      bpf: sockmap, map_release does not hold refcnt for pinned maps
      bpf: sockmap, sk_wait_event needed to handle blocking cases
      bpf: sockmap, fix double page_put on ENOMEM error in redirect path
