It was using the first variation on producing a string representation for a binary flag, one that used the copy of uapi/linux/sched.h with preprocessor tricks that had to be updated everytime a new flag was introduced. Use the more recent scrape script + strarray + strarray__scnprintf_flags() combo. $ tools/perf/trace/beauty/clone.sh | head -5 static const char *clone_flags[] = { [ilog2(0x00000100) + 1] = "VM", [ilog2(0x00000200) + 1] = "FS", [ilog2(0x00000400) + 1] = "FILES", [ilog2(0x00000800) + 1] = "SIGHAND", $ Now we can move uapi/linux/sched.h from tools/include/, that is used for building perf to the scrape only directory tools/perf/trace/beauty/include.

| 48 | * struct clone_args - arguments for the clone3 syscall | ||
| 49 | * @flags: Flags for the new process as listed above. | ||
| 50 | * All flags are valid except for CSIGNAL and | ||
| 51 | * CLONE_DETACHED. | ||
| 52 | * @pidfd: If CLONE_PIDFD is set, a pidfd will be | ||
| 53 | * returned in this argument. | ||
| 54 | * @child_tid: If CLONE_CHILD_SETTID is set, the TID of the | ||
| 55 | * child process will be returned in the child's | ||
| 56 | * memory. | ||
| 57 | * @parent_tid: If CLONE_PARENT_SETTID is set, the TID of | ||
| 58 | * the child process will be returned in the | ||
| 59 | * parent's memory. | ||
| 60 | * @exit_signal: The exit_signal the parent process will be | ||
| 61 | * sent when the child exits. | ||
| 62 | * @stack: Specify the location of the stack for the | ||
| 63 | * child process. | ||
| 64 | * Note, @stack is expected to point to the | ||
| 65 | * lowest address. The stack direction will be | ||
| 66 | * determined by the kernel and set up | ||
| 67 | * appropriately based on @stack_size. | ||
| 68 | * @stack_size: The size of the stack for the child process. | ||
| 69 | * @tls: If CLONE_SETTLS is set, the tls descriptor | ||
| 70 | * is set to tls. | ||
| 71 | * @set_tid: Pointer to an array of type *pid_t. The size | ||
| 72 | * of the array is defined using @set_tid_size. | ||
| 73 | * This array is used to select PIDs/TIDs for | ||
| 74 | * newly created processes. The first element in | ||
| 75 | * this defines the PID in the most nested PID | ||
| 76 | * namespace. Each additional element in the array | ||
| 77 | * defines the PID in the parent PID namespace of | ||
| 78 | * the original PID namespace. If the array has | ||
| 79 | * less entries than the number of currently | ||
| 80 | * nested PID namespaces only the PIDs in the | ||
| 81 | * corresponding namespaces are set. | ||
| 82 | * @set_tid_size: This defines the size of the array referenced | ||
| 83 | * in @set_tid. This cannot be larger than the | ||
| 84 | * kernel's limit of nested PID namespaces. | ||
| 85 | * @cgroup: If CLONE_INTO_CGROUP is specified set this to | ||
| 86 | * a file descriptor for the cgroup. | ||
| 87 | * | ||
| 88 | * The structure is versioned by size and thus extensible. | ||
| 89 | * New struct members must go at the end of the struct and | ||
| 90 | * must be properly 64bit aligned. | ||
