NFSD: nfsd-io-modes: Separate lists (2025-12-03 09:05:14 -0500)
----------------------------------------------------------------
NFSD 6.19 Release Notes
Mike Snitzer's mechanism for disabling I/O caching introduced in
v6.18 is extended to include using direct I/O. The goal is to
further reduce the memory footprint consumed by NFS clients
accessing large data sets via NFSD.
The NFSD community adopted a maintainer entry profile during this
cycle. See
Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst
Work continues on hardening NFSD's implementation of the pNFS block
layout type. This type enables pNFS clients to directly access the
underlying block devices that contain an exported file system,
reducing server overhead and increasing data throughput.
The remaining patches in this pull request are clean-ups and minor
optimizations. Many thanks to the contributors, reviewers, testers,
and bug reporters who participated during the v6.19 NFSD development
cycle.
