Subject: [PATCH bpf 0/3] Three BPF fixes

This set contains three fixes that are mostly JIT and set_memory_*()
related. The third in the series in particular fixes the syzkaller
bugs that were still pending; aside from local reproduction & testing,
also 'syz test' wasn't able to trigger them anymore. I've tested this
series on x86_64, arm64 and s390x, and kbuild bot wasn't yelling either
for the rest. For details, please see patches as usual, thanks!

Daniel Borkmann (3):
  bpf, arm32: fix to use bpf_jit_binary_lock_ro api
  bpf, s390: fix potential memleak when later bpf_jit_prog fails
  bpf: undo prog rejection on read-only lock failure
