This is the followup work of task comm cleanups[1]. In this phase, the hard-coded 16 is replaced by 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. - TASK_COMM_LEN_16 The size must be a fixed-size 16 no matter what TASK_COMM_LEN is. It may be exposed to userspace so we can't change it. 1. https://lore.kernel.org/lkml/20211120112738.45980-1-laoar.shao@xxxxxxxxx/ Changes since v1: - use TASK_COMM_LEN_16 instead of TASK_COMM_LEN in patch #3 (Steven) - avoid changing samples/bpf and bpf/progs (Alexei) 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 (3): elfcore: replace old hard-code 16 with TASK_COMM_LEN_16 cn_proc: replaced old hard-coded 16 with TASK_COMM_LEN_16 tools/perf: replace old hard-coded 16 with TASK_COMM_LEN_16 include/linux/elfcore-compat.h | 8 ++------ include/linux/elfcore.h | 9 ++------- include/linux/sched.h | 5 +++++ include/uapi/linux/cn_proc.h | 4 +++- tools/perf/tests/evsel-tp-sched.c | 8 +++++--- 5 files changed, 17 insertions(+), 17 deletions(-) -- 2.17.1
