[PATCH bpf-next 0/4] bpf: fixes for lockdep and deadlock

2019-01-29 Thread Alexei Starovoitov
In addition to preempt_disable patch for socket filters https://patchwork.ozlabs.org/patch/1032437/ the first three patches fix various lockdep false positives. Last patch fixes potential deadlock in stackmap access from tracing bpf prog and from syscall. Alexei Starovoitov (3): bpf: fix lockdep
