David Howells 0bdaea9017 VFS: Split inode_permission() 
Split inode_permission() into inode- and superblock-dependent parts.

This is aimed at unionmounts where the superblock from the upper layer has to
be checked rather than the superblock from the lower layer as the upper layer
may be writable, thus allowing an unwritable file from the lower layer to be
copied up and modified.
