Linux 7.3 Looks Like It Will Upstream FailFS
WHY IT MATTERS
FailFS provides a deliberately failing filesystem implementation, allowing engineers to test error‑handling paths in code that interacts with storage. Having it in the main kernel eliminates the need for external mock filesystems during development and CI.
Written by elseif from the cluster below · every claim links back to a sourceThe three things worth knowing
01
FailFS is a minimal pseudo‑filesystem designed to fail operations on demand.
02
It is being added to Linux 7.3 alongside the already merged NULLFS.
03
Its upstream inclusion gives developers a built‑in tool for filesystem error testing.
