The below set of patches implement open by handle support using exportfs
operations. This allows user space application to map a file name to file
handle and later open the file using handle. This should be usable
for userspace NFS [1] and 9P server [2]. XFS already support this with the ioctls


git repo for the patchset at:
git:// open-by-handle

Test case can be found at

Changes from V19:
a) Drop handle based chown, xattr, utimes syscalls
b) Rebased to latest linus kernel (050026feae5bd4fe2db4096b63b15abce7c47faa)
