Subject: [PATCH v2 29/39] fs: add helpers for idmap mounts
Extend some inode methods with an additional user namespace argument. A
filesystem that is aware of idmapped mounts will receive the user namespace
the mount has been marked with. This can be used for additional permission
checking and also to enable filesystems to translate between uids and gids
if they need to. We have implemented all relevant helpers in earlier
patches.
As requested we simply extend the exisiting inode method instead of
introducing new ones. This is a little more code churn but it's mostly
mechanical and doens't leave us with additional inode methods.

/* v2 */
- Christoph Hellwig:
- Don't pollute the vfs with additional helpers simply extend the existing
inode methods with an additional argument and switch all callers.
