This patchset is for VFS. Of course, it depends on my previous vmsplice
patchset.

I fix some problems in my previous patchset.

1. Fix problem with CLASS(fd, f)(fd). See first patch for details.
This is probably not so important, but I fix it anyway.

2. Change "unsigned long" back to "int". See second patch for details.
Again, this is probably not important, but I want to fix this anyway.

3. Fix that LTP vmsplice01 bug.

See patches for details.

Please, run that LTP vmsplice01 test again.

How to proceed with this patch set given that, as Joanne explains [1], libfuse
seems to modify the data in the page after splicing, so really depending on
vmsplice() reading data that we update through the page tables -- the page
actually being pinned.

IIUC, reverting the patch might be required. Or maybe Christian can still simply
drop the topic branch entirely.
