Hi Al,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git overlayfs-viro
This has an assortment of fixes and cleanups for overlayfs.
It also touches the VFS:
- add the vfs_get_link() helper for calling i_op->get_link();
- fix mnt_want_write_file() to freeze protect the underlying sb instead of
overlay sb;
- allow vfs_clone_file_range() to be called by overlayfs.
None of the above should have any effect on filesystems other than overlayfs.
Thanks,
Miklos
