[ANNOUNCE] ovl: overlayfs-next updated to d1512c40431a

[Amir Goldstein]

Hi all,

The overlayfs-next branch of the overlayfs repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs.git

has been updated.

The head of the overlayfs-next branch is commit:

  d1512c40431a ("ovl: Add documentation on nesting of overlayfs mounts")

The updated head contains the following patch sets:

- Rename and export some vfs helpers [1] (merged via vfs tree)

- Overlayfs aio cleanups [2] (prep work for FUSE passthrough helpers)

- Overlayfs lock ordering changes [3] (prep work for write-safe fsnotify
  permission events)

- Add support for nesting overlayfs private xattrs (Alex) [4]

The new code was tested using fstests including new tests written
by Alex, which are available on his xfstests tree [5].

Miklos,

Each of the overlayfs patch sets include changes that address your
review comments from earlier revision, but niether have an explicit ACK
from you on the final version (as posted in the links below).

We still have plently of time until the merge window for you to review
those patches, so I decided to expose them to linux-next testing.
Please shout if you think that any of the patches need extra time for
review or not acceptable for consideration to 6.7 in their current form.

Thanks,
Amir.
