Linus Torvalds 7cf035cc83 Merge tag 'vfs-5.8-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull DAX updates part three from Darrick Wong:
 "Now that the xfs changes have landed, this third piece changes the
  FS_XFLAG_DAX ioctl code in xfs to request that the inode be reloaded
  after the last program closes the file, if doing so would make a S_DAX
  change happen. The goal here is to make dax access mode switching
  quicker when possible.

  Summary:

   - Teach XFS to ask the VFS to drop an inode if the administrator
     changes the FS_XFLAG_DAX inode flag such that the S_DAX state would
     change. This can result in files changing access modes without
     requiring an unmount cycle"

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.
