| |
Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-linus
Fix two more POSIX ACL bugs introduced in 4.8 and add a missing fsync during copy up to prevent possible data loss.
Also introduce the concept of feature flags to allow backward incompatible changes to the overlay format. This should have been there from day one; the best we can do now is backport to stable kernels. Add the check for features without adding any actual features yet.
Thanks, Miklos
