I've just released mount-insight v0.1 https://gitlab.com/zygoon/mount-insight/-/releases/v0.1
Here's an excerpt from the release notes:
This is the initial release of mount-insight, a tool created to explore and display the data provided by the statmount system call.
Some features are only going to work once Linux 6.15 is released. The code needs to see matching, up-to-date headers for userspace Linux APIs as well.
