Merge tag 'ovl-update-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs

Pull overlayfs updates from Amir Goldstein:

 - Overlayfs aio cleanups and fixes

   Cleanups and minor fixes in preparation for factoring out of
   read/write passthrough code.

 - Overlayfs lock ordering changes

   Hold mnt_writers only throughout copy up instead of a long lived
   elevated refcount.

 - Add support for nesting overlayfs private xattrs

   There are cases where you want to use an overlayfs mount as a
   lowerdir for another overlayfs mount. For example, if the system
   rootfs is on overlayfs due to composefs, or to make it volatile (via
   tmpfs), then you cannot currently store a lowerdir on the rootfs,
   because the inner overlayfs will eat all the whiteouts and overlay
   xattrs. This means you can't e.g. store on the rootfs a prepared
   container image for use with overlayfs.

   This adds support for nesting of overlayfs mounts by escaping the
   problematic features and unescaping them when exposing to the
   overlayfs user.

 - Add new mount options for appending lowerdirs

* tag 'ovl-update-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs:
  ovl: add support for appending lowerdirs one by one

  ovl: Add OVL_XATTR_TRUSTED/USER_PREFIX_LEN macros
  ovl: Move xattr support to new xattrs.c file
  ovl: do not encode lower fh with upper sb_writers held
  ovl: do not open/llseek lower file with upper sb_writers held
  ovl: reorder ovl_want_write() after ovl_inode_lock()
  ovl: split ovl_want_write() into two helpers
  ovl: add helper ovl_file_modified()
  ovl: protect copying of realinode attributes to ovl inode
  ovl: punt write aio completion to workqueue
  ovl: propagate IOCB_APPEND flag on writes to realfile
  ovl: use simpler function to convert iocb to rw flags

README

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.
