Chuck Lever led a filesystem session at the
2023 Linux Storage, Filesystem,
Memory-Management and BPF Summit on the Linux NFS server, which is also
known as NFSD. He wanted to talk about converting the network filesystem
to use iomap; that kind of
conversion
was the topic of the previous session at
the summit. Beyond that, he wanted to discuss using folios, which has been
a frequent topic at recent LSFMM+BPF gatherings, including this year.
