This is the followup work of task comm cleanups[1]. In this phase, the hard-coded 16 is replaced by either TASK_COMM_LEN or TASK_COMM_LEN_16, to make it grepable. The difference between this two marcos is: - TASK_COMM_LEN The size should be same with the TASK_COMM_LEN defined in linux/sched.h. For the src file which can't include linux/sched.h, a macro with the the same name is defined in this file specifically. - TASK_COMM_LEN_16 The size must be a fixed-size 16. It may be exposed to userspace so we can't change it. In order to include vmlinux.h in bpf progs under sample/bpf or tools/testing/selftests/bpf, some structs are renamed and some included headers are removed. 1. https://lore.kernel.org/lkml/20211120112738.45980-1-laoar.shao@xxxxxxxxx/ Cc: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxxxx> Cc: Arnaldo Carvalho de Melo <arnaldo.melo@xxxxxxxxx> Cc: Alexei Starovoitov <alexei.starovoitov@xxxxxxxxx> Cc: Andrii Nakryiko <andrii.nakryiko@xxxxxxxxx> Cc: Michal Miroslaw <mirq-linux@xxxxxxxxxxxx> Cc: Peter Zijlstra <peterz@xxxxxxxxxxxxx> Cc: Steven Rostedt <rostedt@xxxxxxxxxxx> Cc: Matthew Wilcox <willy@xxxxxxxxxxxxx> Cc: David Hildenbrand <david@xxxxxxxxxx> Cc: Al Viro <viro@xxxxxxxxxxxxxxxxxx> Cc: Kees Cook <keescook@xxxxxxxxxxxx> Cc: Petr Mladek <pmladek@xxxxxxxx> Yafang Shao (5): elfcore: replace old hard-code 16 with TASK_COMM_LEN_16 cn_proc: replaced old hard-coded 16 with TASK_COMM_LEN_16 samples/bpf/tracex2: replace hard-coded 16 with TASK_COMM_LEN tools/perf: replace hard-coded 16 with TASK_COMM_LEN bpf/progs: replace hard-coded 16 with TASK_COMM_LEN include/linux/elfcore-compat.h | 8 ++------ include/linux/elfcore.h | 9 ++------- include/linux/sched.h | 5 +++++ include/uapi/linux/cn_proc.h | 4 +++- samples/bpf/tracex2_kern.c | 3 ++- samples/bpf/tracex2_user.c | 3 ++- tools/perf/tests/evsel-tp-sched.c | 8 +++++--- tools/testing/selftests/bpf/prog_tests/ringbuf.c | 9 +++++---- .../testing/selftests/bpf/prog_tests/ringbuf_multi.c | 8 +++++--- .../selftests/bpf/prog_tests/sk_storage_tracing.c | 3 ++- .../testing/selftests/bpf/prog_tests/test_overhead.c | 3 ++- .../selftests/bpf/prog_tests/trampoline_count.c | 3 ++- .../selftests/bpf/progs/test_core_reloc_kernel.c | 11 +++++------ tools/testing/selftests/bpf/progs/test_ringbuf.c | 8 ++++---- .../testing/selftests/bpf/progs/test_ringbuf_multi.c | 8 ++++---- .../selftests/bpf/progs/test_sk_storage_tracing.c | 4 ++-- 16 files changed, 52 insertions(+), 45 deletions(-) -- 2.17.1
