Hi,
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 XFS_IOC_PATH_TO_HANDLE and XFS_IOC_OPEN_BY_HANDLE.

git repo for the patchset at: git://git.kernel.org/pub/scm/linux/kernel/git/kvaneesh/linux-open-handle.git open-by-handle
Test case can be found at http://git.kernel.org/?p=fs/ext2/kvaneesh/handle-test.git git://git.kernel.org/pub/scm/fs/ext2/kvaneesh/handle-test.git
Changes from V22: a) Add support for O_PATH open flag b) Add support "" names in *at syscalls c) Add support O_PATH descriptor in few selective syscalls like stat, chown, chmod and dup
NOTE: v23-25 can be found in the git repo
