This is a note to let you know that I've just added the patch titled perf off_cpu: Fix a typo in BTF tracepoint name, it should be 'btf_trace_sched_switch' to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: perf-off_cpu-fix-a-typo-in-btf-tracepoint-name-it-sh.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 66e76c43be2095f69c72c544e2b8724991da4d9d Author: Namhyung Kim <namhyung@xxxxxxxxxx> Date: Thu Dec 8 10:26:36 2022 -0800 perf off_cpu: Fix a typo in BTF tracepoint name, it should be 'btf_trace_sched_switch' [ Upstream commit 167b266bf66c5b93171011ef9d1f09b070c2c537 ] In BTF, tracepoint definitions have the "btf_trace_" prefix. The off-cpu profiler needs to check the signature of the sched_switch event using that definition. But there's a typo (s/bpf/btf/) so it failed always.
