Hi, all. I'd like to maintain bpf subsystem and tracing(ftrace, kprobes) subsystem in anolis cloud kernel.

My work in ANCK is mainly debug/tracing which involves bpf, ftrace, kprobes, kdump, etc. I am also the default assignee of debugability for openanolis ANCK bugzilla.

Here are some of my contributions:

Backport bpf features(submit and review) to ANCK 4.19: flow-dissector, per-cpu cgroup storage, sk lookup, sockmap, btf, line_info, func_info, tc_tunning, sysctl hook, bpf spinlock, global data, bounded loop, CO-RE. (review [1-14,39-41,45-46], submit [15-38,42-44,47-55])
Improve bpf subsystem code test coverage ration by fixing selftest, adding testcase. Code test coverage ratio for ANCK 4.19 increase from 64% to 83%, for ANCK 5.10 increase from 72% to 85%.
Backport bpf bug fixes [59] and review bpf and ftrace patches. [60-63]
Contribute ftrace patch to upstream and backport for ANCK. [64,65]

The list of files/directories I want to maintain are as follows:

include/uapi/linux/bpf*

kernel/bpf/

kernel/trace/bpf_trace.c

lib/test_bpf.c
