The scenario could trigger on any user of RCU_NOCB # (mostly Android but also nohz_full) # # - Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking # some RCU-Tasks and RCU-Tasks-Trace expectations as to what # exactly is an idle task. This resulted in potential spurious # stalls and warnings. # # * tag 'rcu-fixes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: # rcu/tasks-trace: Handle new PF_IDLE semantics # rcu/tasks: Handle new PF_IDLE semantics # rcu: Introduce rcu_cpu_online() # rcu: Break rcu_node_0 --> &rq->__lock order # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 90450a06162e6c71ab813ea22a83196fe7cff4bc # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/fsp2_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/linus_44x_fsp2_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/kernel/bpf/task_iter.c: In function 'bpf_iter_css_task_new': /kisskb/src/kernel/bpf/task_iter.c:917:14: error: 'CSS_TASK_ITER_PROCS' undeclared (first use in this function) 917 | case CSS_TASK_ITER_PROCS | CSS_TASK_ITER_THREADED: | ^~~~~~~~~~~~~~~~~~~ /kisskb/src/kernel/bpf/task_iter.c:917:14: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/kernel/bpf/task_iter.c:917:36: error: 'CSS_TASK_ITER_THREADED' undeclared (first use in this function) 917 | case CSS_TASK_ITER_PROCS | CSS_TASK_ITER_THREADED: | ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/kernel/bpf/task_iter.c:925:60: error: invalid application of 'sizeof' to incomplete type 'struct css_task_iter' 925 | kit->css_it = bpf_mem_alloc(&bpf_global_ma, sizeof(struct css_task_iter)); | ^~~~~~ /kisskb/src/kernel/bpf/task_iter.c:928:9: error: implicit declaration of function 'css_task_iter_start'; did you mean 'task_seq_start'?
