[AFS]: Add "directory write" support.
Add support for the create, link, symlink, unlink, mkdir, rmdir and rename VFS operations to the in-kernel AFS filesystem. Also: (1) Fix dentry and inode revalidation. d_revalidate should only look at state of the dentry. Revalidation of the contents of an inode pointed to by a dentry is now separate. (2) Fix afs_lookup() to hash negative dentries as well as positive ones. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
