What steps will reproduce the bug?

mkdir repro
cd repro
ln -s a b && ln -s b a
node -e 'fs.rmSync("a")'
cd ..
rm -r repro

How often does it reproduce? Is there a required condition?

Always. No.

What is the expected behavior?

Can delete symlinks that form a loop.

What do you see instead?

This error

Uncaught Error: ELOOP: too many symbolic links encountered, stat 'a'
    at Object.statSync (node:fs:1596:3)
    at __node_internal_ (node:internal/fs/utils:804:8)
    at Object.rmSync (node:fs:1272:13) {
  errno: -62,
  syscall: 'stat',
  code: 'ELOOP',
  path: 'a'
}

Additional information

This stat call should probably be a lstatcall.

node/lib/internal/fs/utils.js

Line 772 in 1b97188

lazyLoadFs().stat(path, (err, stats) => {

Workaround:

try {
    await rm(path, {...});
} catch (e) {
    if ('code' in e && e.code === 'ELOOP') {
         await unlink(p);
     }
}

Thanks for the report. Would you be interested in sending a PR to fix this?
