Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a build error in sk_reuseport_convert_ctx_access() when
compiling with clang which cannot resolve hweight_long() at
build time inside the BUILD_BUG_ON() assertion, from Stefan.
2) Several fixes for BPF sockmap, four of them in getting the
bpf_msg_pull_data() helper to work, one use after free case
in bpf_tcp_close() and one refcount leak in bpf_tcp_recvmsg(),
from Daniel.
3) Another fix for BPF sockmap where we misaccount sk_mem_uncharge()
in the socket redirect error case from unwinding scatterlist
twice, from John.

Thanks a lot!
