Is there something like USN Journal in a Linux file system?

Question

I often use everything (search tool) on Windows. It uses the USN Journal to speed up file name searches.

Does the Linux file system (ext4, xfs, btrfs, etc.) have a similar function for the USN log?

Answer 1

Journal USN allows Windows program to keep track of file changes.

A Linux program can do the same with inotify . This allows the program to be notified of every file change.

This is not a function of any particular file system, but the level of the kernel file system, so it works with any file system.
