This series enables the relinking of unlinked files for the purpose of
enabling checkpoint/restart of tasks with open unlinked files. It
relies on Namhyung Kim's sys-wrapper patches to provide unlink and
rmdir calls for sys_restart.

There are two patches with long descriptions. Patch 3 describes
what we want from the VFS -- relinking support -- and uses ext3/4 as an
example of what kinds of changes that entails. Patch 5 then details
how we intend to use relinking during checkpoint to enable restart
of tasks that have unlinked files open.

Applies to Oren's ckpt-v22-dev branch. I chose Oren's tree because
I assume people want to see code showing how relinking will be used.
If this is wrong I'll be happy to respin these patches against a
more recent branch of mainline.
