Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-linus
Because copy up can take a long time, serialized copy ups could be a big
performance bottleneck. This update allows concurrent copy up of regular files
eliminating this potential problem. There are also minor fixes.
Thanks,
Miklos
