Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix verifier precision tracking with BPF-to-BPF calls, from Alexei.
2) Fix a use-after-free in prog symbol exposure, from Daniel.
3) Several s390x JIT fixes plus BE related fixes in BPF kselftests, from Ilya.
4) Fix memory leak by unpinning XDP umem pages in error path, from Ivan.
5) Fix a potential use-after-free on flow dissector detach, from Jakub.
6) Fix bpftool to close prog fd after showing metadata, from Quentin.
7) BPF kselftest config and TEST_PROGS_EXTENDED fixes, from Anders.
