[$] Long-duration stress-testing for filesystems

Testing filesystems is a frequent topic at
the Linux Storage, Filesystem,
Memory Management, and BPF Summit (LSFMM+BPF); the 2025 edition was no
exception. Boris Burkov led a filesystem-track session to discuss
stress-testing filesystems—and running those tests for lengthy periods. He
reviewed what he has been doing when testing filesystems and wanted to
gather ideas for what could be done to catch more bugs before the
filesystems hit production.
