[PATCH 5/7] Documentation, arch, fs: Remove leftovers from fscache object list
From: Alexandre Ghiti <hidden>
Date: 2021-11-05 15:49:01
Also in:
linux-arm-kernel, linux-cifs, linux-doc, linux-mips, linuxppc-dev, lkml
Subsystem:
arm port, documentation, filesystems (vfs and infrastructure), filesystems [netfs library], the rest · Maintainers:
Russell King, Jonathan Corbet, Alexander Viro, Christian Brauner, David Howells, Paulo Alcantara, Linus Torvalds
A few references to the fscache object list were left in the
Documentation, some arch defconfigs and in fs: remove them since this
config does not exists anymore.
Fixes: 58f386a73f16 ("fscache: Remove the object list procfile")
