Daniel Borkmann says: ==================== Small set of fixes in order to restrict BPF helpers for tracing which are broken on archs with overlapping address ranges as per discussion in [0]. I've targetted this for -bpf tree so they can be routed as fixes. Thanks! v1 -> v2: - switch to reusable %pks, %pus format specifiers (Yonghong) - fixate %s on kernel_ds probing for archs with overlapping addr space [0] https://lore.kernel.org/bpf/CAHk-=wjJKo0GVixYLmqPn-Q22WFu0xHaBSjKEo7e7Yw72y5SPQ@mail.gmail.com/T/ ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
