Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a umem memory leak on cleanup in AF_XDP, from Björn.
2) Fix BTF to properly resolve forward-declared enums into their corresponding
full enum definition types during deduplication, from Andrii.
3) Fix libbpf to reject invalid flags in xsk_socket__create(), from Magnus.
4) Fix accessing invalid pointer returned from bpf_tcp_sock() and
bpf_sk_fullsock() after bpf_sk_release() was called, from Martin.
5) Fix generation of load/store DW instructions in PPC JIT, from Naveen.
6) Various fixes in BPF helper function documentation in bpf.h UAPI header
used to bpf-helpers(7) man page, from Quentin.
7) Fix segfault in BPF test_progs when prog loading failed, from Yonghong.
