Namhyung Kim	5a433107fa	perf trace: Update beautifier script for clone flags ... According to the change in the sched.h, update the script to generate the flags array like below. Note that '+1' is needed to detect bitmask pattern at index 0. $ cat tools/perf/trace/beauty/generated/clone_flags_array.c static const char *clone_flags[] = { [ilog2(0x00000100) + 1] = "VM", [ilog2(0x00000200) + 1] = "FS", [ilog2(0x00000400) + 1] = "FILES", [ilog2(0x00000800) + 1] = "SIGHAND", [ilog2(0x00001000) + 1] = "PIDFD", [ilog2(0x00002000) + 1] = "PTRACE", [ilog2(0x00004000) + 1] = "VFORK", [ilog2(0x00008000) + 1] = "PARENT", [ilog2(0x00010000) + 1] = "THREAD", [ilog2(0x00020000) + 1] = "NEWNS", [ilog2(0x00040000) + 1] = "SYSVSEM", [ilog2(0x00080000) + 1] = "SETTLS", [ilog2(0x00100000) + 1] = "PARENT_SETTID", [ilog2(0x00200000) + 1] = "CHILD_CLEARTID", [ilog2(0x00400000) + 1] = "DETACHED", [ilog2(0x00800000) + 1] = "UNTRACED", [ilog2(0x01000000) + 1] = "CHILD_SETTID", [ilog2(0x02000000) + 1] = "NEWCGROUP", [ilog2(0x04000000) + 1] = "NEWUTS", [ilog2(0x08000000) + 1] = "NEWIPC", [ilog2(0x10000000) + 1] = "NEWUSER", [ilog2(0x20000000) + 1] = "NEWPID", [ilog2(0x40000000) + 1] = "NEWNET", [ilog2(0x80000000) + 1] = "IO", [ilog2(0x00000080) + 1] = "NEWTIME", [32 + 1] = "CLEAR_SIGHAND", [33 + 1] = "INTO_CGROUP", [34 + 1] = "AUTOREAP", [35 + 1] = "NNP", [36 + 1] = "PIDFD_AUTOKILL", [37 + 1] = "EMPTY_MNTNS", }; This was found by Sashiko during review.

Arnaldo Carvalho de Melo	2316ef5891	perf beauty: Introduce scrape script for 'clone' syscall 'flags' argument ... 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.
