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 scraper 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 scrap only directory tools/perf/trace/beauty/include.
