fsstack: struct path

[Josef Sipek <jsipek@fsl.cs.sunysb.edu>]

Few weeks ago, I noticed that fs/namei.c defines struct path:

struct path {
	struct vfsmount *mnt;
	struct dentry *dentry;
};

I think it would make sense to move it into include/linux/ as it is quite
useful (and it would discourage the (ab)use of struct nameidata.)

The fsstack code could benefit from it as the stackable fs dentries have to
keep track of the lower dentry as well as the lower vfsmount.

One, rather unfortunate, fact is that struct path is also defined in
include/linux/reiserfs_fs.h as something completely different - reiserfs
specific.

Any thoughts?
