[$] A distributed filesystem for archival systems: ngnfs

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