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.

[2] http://thread.gmane.org/gmane.comp.emulators.qemu/68992

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 V18:
a) Drop open on symlink patch
b) Drop other patches that added support for NULL pathname in *at syscalls
c) Add new handle based syscalls. All of them are restricted to CAP_DAC_READ_SEARCH
