fs.watch recursive on Linux emits spurious rename events for sibling files/directories prefixed by related paths on deletion

[Sodium-Aluminate]

Version

v24.2.0 (from archlinux) and v24.1.0 (from nwjs)

Platform

Linux ****** 6.15.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Tue, 10 Jun 2025 21:32:33 +0000 x86_64 GNU/Linux

Subsystem

fs

What steps will reproduce the bug?

1. open 2 window, prepare test files in the first window:

mkdir -p foo_bar/somedir
touch foo_bar/file.txt
mkdir foo
touch foo_

2. open a node repl in the second window:

fs.watch(".", { recursive: true }, console.log);

3. keep the node running, back to the first window:

rmdir foo

Observed output in the second window:

rename foo
rename foo_
rename foo_bar
rename foo_bar/file.txt
rename foo_bar/somedir

and then:

rm foo_

Observed output in the second window:

rename foo_
rename foo_bar
rename foo_bar/file.txt
rename foo_bar/somedir

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

N/A

What is the expected behavior? Why is that the expected behavior?

expected not send the unrelated event(in test case, foo_bar is unchanged, but we got a fake event)

What do you see instead?

(already attached output in reproduce steps)
