NFS: More fine grained attribute tracking
Currently, if the NFS_INO_INVALID_ATTR flag is set, for instance by a call to nfs_post_op_update_inode_locked(), then it will not be cleared until all the attributes have been revalidated. This means, for instance, that NFSv4 writes will always force a full attribute revalidation. Track the ctime, mtime, size and change attribute separately from the other attributes so that we can have nfs_post_op_update_inode_locked() set them correctly, and later have the cache consistency bitmask be able to clear them.
