It should come as no surprise that a gathering of filesystem developers
would discuss filesystem testing; it has been a mainstay of the Linux Storage,
Filesystem, Memory Management, and BPF Summit over the years and the
2026 summit was no exception. Ted Ts’o led the discussion this time; he
had a few different topics to raise, including his perception of increasing
regressions for ext4 in the stable kernels and what can be done to help
reduce them. As with other similar
sessions at the summit over the years,
there is a lot of interest in collaborating on test inputs and outputs, but
finding a way to centralize that information has so far eluded the
filesystem community.
