- Introduce DONTCACHE flags for dentries and inodes. This hint will
cause the VFS to drop the associated objects immediately after the
last put, so that we can change the file access mode (DAX or page
cache) on the fly.

Pull DAX updates part two from Darrick Wong:
"This time around, we're hoisting the DONTCACHE flag from XFS into the
VFS so that we can make the incore DAX mode changes become effective
sooner.
We can't change the file data access mode on a live inode because we
don't have a safe way to change the file ops pointers. The incore
state change becomes effective at inode loading time, which can happen
if the inode is evicted. Therefore, we're making it so that
filesystems can ask the VFS to evict the inode as soon as the last
holder drops.
The per-fs changes to make this call this will be in subsequent pull
requests from Ted and myself.
Summary:
- Introduce DONTCACHE flags for dentries and inodes. This hint will
cause the VFS to drop the associated objects immediately after the
last put, so that we can change the file access mode (DAX or page
cache) on the fly"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
