Subject: [PATCH 00/14] cifs: Iterators, netfslib and folios
Date: Thu, 07 Apr 2022 00:02:30 +0100 [thread overview]
Message-ID: <164928615045.457102.10607899252434268982.stgit@warthog.procyon.org.uk> (raw)
Here's a set of patches to make the following changes to the cifs
filesystem driver:
(1) Convert cifs to use I/O iterators to pass data/buffers from the the VM
interface layer down to the socket rather than passing page lists
about.
(2) Convert cifs to use netfslib for buffered and direct read operations.
(3) A partial conversion to folios.
This branch is built on top of my netfs-lib branch[1].
The patches can be found here also:
