Subject: Extent to files

Message-ID: <20191104113519.htdigcg6lzbes6v7@T580.localdomain> (raw)

I did a ioctl(FICLONE) IOCTL-FICLONERANGE(2) at some point later I want to be
able to check if the new file still shares all its physical storage with just
knowing the name of the new file.

I found some people suggesting to compare the files extents.

But the implementation I looked at knew both files used in the comparison,
so I was wondering if there a way to get all files that references a extent
in user space?

In reality I want a count off clones/(identical files) to a given file
in user space.
