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:
0a3bf81dbcb2 ("ovl: auto generate uuid for new overlay filesystems")
The updated head contains the following patch sets:
- Add support for fs-verity checking of lowerdata -
including fixes to address review comments of Eric Biggers on v5 [1]
- Report overlayfs file ids with fanotify (v2) [2]
The new code was tested using fstests including new tests written
by Alex and myself, which are available on my xfstests tree [3].
Test setup scripts for testing the verity feature are available
in my xfstests-bld tree [4].
Thanks,
Amir.
