We've added 11 non-merge commits during the last 8 day(s) which contain a total of 11 files changed, 83 insertions(+), 74 deletions(-). The main changes are: 1) Fix strncpy_from_kernel_nofault() to prevent out-of-bounds writes, from Alban Crequy. 2) Fix for bpf_prog_test_run_skb() to prevent wrong alignment, from Baisong Zhong. 3) Switch BPF_DISPATCHER to static_call() instead of ftrace infra, with a small build fix on top, from Peter Zijlstra and Nathan Chancellor. 4) Fix memory leak in BPF verifier in some error cases, from Wang Yufen. 5) 32-bit compilation error fixes for BPF selftests, from Pu Lehui and Yang Jihong. 6) Ensure even distribution of per-CPU free list elements, from Xu Kuohai. 7) Fix copy_map_value() to track special zeroed out areas properly, from Xu Kuohai.
