v7: - Add init for `iter` in bpf_pidns_nr_tasks() - Mark `__maybe_unused` for `pol` in blkcg_get_one_stat_v1() - Remove unused `RET_SKIP` in bpf progs code v6: - Remove bpf_mem_direct_map(). Export direct_pages_count[] and get it via bpf_x86_direct_pages(). v5: - Gather bpf_arm64_cpu_have_feature() into arch/arm64/kernel/bpf-rvi.c v4: - Fix compile failure of bpf_mem_failure() when CONFIG_MEMORY_FAILURE=n - Move iterator target for diskstats & partitions into block/bpf-rvi.c, to avoid unexpected "kABI changes" (actually no) v3: - Optimize swaptotal's estimation and make it a stand-alone function v2: - Remove pidns's refcount from the loadavg global list. - Optimize calculation of swap{total,usage,free} for swap and meminfo - Fix a put_task_struct() missing for bpf_disk_seqf_start() - Remove ineffective build control in samples/bpf/Makefile - Clean up some commented code --- Common supports: bpf-rvi: cpuset: Fix missing of return for !tsk in
