Add myself as scheduler maintainer in anolis cloud kernel

by Tianchen Ding

Hi, all. I'd like to maintain scheduler subsystem in anolis cloud kernel. Here are some of my contributions : 1. Co-develop of cpu burst in upstream. [1] 2. Many improvements and bugfixes in upstream. [2-8] 3. Backport core scheduling features to ANCK 5.10 [9] 4. Backport cgroup SCHED_IDLE support to ANCK 5.10 [10-11] 5. Introduce forceidled time to improve observability. [12] 6. Introduce introduce fine-grained priority for GI 2.0 [13] 7. Co-develop if ACPU. [14] 8. Backport bugfixes. [15-17] 9. Review ANCK own patches like group identity, group balancer, core scheduling improvement, rich container, etc. 10. In future: backport and maintain EEVDF bottom half and sched_ext to ANCK 6.6 PS: The list of files/directories I want to maintain is as follows: kernel/sched/ include/linux/sched.h include/linux/sched/ include/uapi/linux/sched.h include/linux/preempt.h include/linux/wait.h kernel/fork.c kernel/exit.c kernel/cpu.c kernel/cgroup/cpuset.c kernel/cgroup/rstat.c kernel/smp.c kernel/sys.c kernel/signal.c kernel/hung_task.c kernel/workqueue.c tools/testing/selftests/sched/ fs/proc/base.c fs/proc/stat.c fs/proc/array.c fs/proc/uptime.c Documentation/RCU/ kernel/rcu/ include/linux/rcu* Documentation/locking/ kernel/locking/ include/linux/lockdep.h include/linux/spinlock*.h arch/*/include/asm/spinlock*.h include/linux/rwlock*.h include/linux/mutex*.h include/linux/rwsem*.h include/linux/seqlock.h lib/locking*.[ch] tools/testing/selftests/locking/ include/asm-generic/futex.h include/linux/futex.h include/uapi/linux/futex.h kernel/futex.c tools/perf/bench/futex* tools/testing/selftests/futex/ [1] https://lore.kernel.org/all/20210621092800.23714-1-changhuaixin@linux.aliba… [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [3] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [4] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [5] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [6] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [7] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [8] https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=faa4… [9] https://gitee.com/anolis/cloud-kernel/pulls/2077 [10] https://gitee.com/anolis/cloud-kernel/pulls/2185 [11] https://gitee.com/anolis/cloud-kernel/pulls/2250 [12] https://gitee.com/anolis/cloud-kernel/pulls/2425 [13] https://gitee.com/anolis/cloud-kernel/pulls/2440 [14] https://gitee.com/anolis/cloud-kernel/pulls/2260 [15] https://gitee.com/anolis/cloud-kernel/pulls/3516 [16] https://gitee.com/anolis/cloud-kernel/pulls/3549 [17] https://gitee.com/anolis/cloud-kernel/pulls/3555

Add myself as maintainer of bpf and tracing in anolis cloud kernel

by Yuanhe Shu

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: 1. 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]) 2. 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%. 3. Backport bpf bug fixes [59] and review bpf and ftrace patches. [60-63] 4. Contribute ftrace patch to upstream and backport for ANCK. [64,65] The list of files/directories I want to maintain are as follows: Documentation/bpf/ include/linux/bpf* include/uapi/linux/bpf* kernel/bpf/ kernel/trace/bpf_trace.c lib/test_bpf.c samples/bpf/
