To silence this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/fs.h' differs from latest version at 'include/uapi/linux/fs.h'
diff -u tools/include/uapi/linux/fs.h include/uapi/linux/fs.h
Due to just two comments added by:
Fixes: 578bdaabd015 ("crypto: speck - remove Speck")
So nothing that entails changes in tools/, that so far uses fs.h to
generate the mount and umount syscalls 'flags' argument integer->string
tables with:
$ tools/perf/trace/beauty/mount_flags.sh
static const char *mount_flags[] = {
[4096 ? (ilog2(4096) + 1) : 0] = "BIND",
<SNIP>
[30 + 1] = "ACTIVE",
[31 + 1] = "NOUSER",
};
$
