Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-linus
In addition to bug fixes and cleanups there are two new features from Amir:
- Consistent inode number support for the case when layers are not all on
the same filesystem (feature is dubbed "xino").
- Optimize overlayfs file handle decoding. This one touches the exportfs
interface to allow detecting the disconnected directory case.
Most of the code has been sitting in -next for a while now, but was rebased
due to a bug fix coming in yesterday. I decided in favor of rebasing on
top of that fix to allow automatic stable backporting.
Thanks,
Miklos
