[PATCH v2 0/5] Prep patches for porting overlayfs to new mount api

[Amir Goldstein <amir73il@gmail.com>]

Miklos,

Following some more cleanup patches that make Christian's new mount api
patches smaller and easier to review.

I had rebased Christain's patches over these cleanups and pushed the
result to github branch fs-overlayfs-mount_api [1].

The v1 prep patches had a bug with xino option parsing that resulted in
some tests being skipped (not failing) and I had only noticed the
skipped test after posting v1.

The v2 prep patches + new mount api patches have passed all the tests
with no new tests skipped.

In addition to running the tests with the default kernel config, I also
ran the tests with the following non-default configs (individually):

1) CONFIG_OVERLAY_FS_REDIRECT_DIR=y
2) CONFIG_OVERLAY_FS_REDIRECT_ALWAYS_FOLLOW=n
3) CONFIG_OVERLAY_FS_XINO_AUTO=y


Thanks.
Amir.

Changes since v1:
- Fix xino opt name table vs. enum order
- Add cleanup patch for xino
- Add cleanup of share_whiteout state
- Add cleanup patch for ovl_get_root()
