[$] A distributed filesystem for archival systems: ngnfs

A new filesystem was the topic of a session led by Zach Brown atthe 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit(LSFMM+BPF). The ngnfsfilesystem is not a "next generation" NFS, as might be guessed from thename; Brown said that he did not think about that linkage("I hate naming so much") until it was pointed out to him by ChuckLever in an email. It is, instead, a filesystem for enormous data setsthat are mostly stored offline.
