pnfs: add pnfs_report_layoutstat helper function
Probably caused by the unusual defconfig having:

New breakage seen in linux-next today:
ERROR: "__xchg_called_with_bad_pointer" [fs/nfs/flexfilelayout/nfs_layout_flexfiles.ko] undefined!
ERROR: "__cmpxchg_called_with_bad_pointer" [fs/nfs/flexfilelayout/nfs_layout_flexfiles.ko] undefined!
make[2]: *** [__modpost] Error 1
make[1]: *** [modules] Error 2
I tried to reproduce it locally so I could run a bisect,
but it must be toolchain specific because I don't see it.
Paul.

Thanks Paul! It was reported by kbuild test robot and a fix has been
sent to linux-nfs list.
Cheers,
Tao

Presumably this is the same thing; showing up in i386 and elsewhere:
fs/nfs/flexfilelayout/flexfilelayout.c:444:15: error: call to

fs/nfs/flexfilelayout/flexfilelayout.c:464:2: error: call to

Sigh. It looks as if xchg() and cmpxchg() are not available for 64-bit
integers on sparc32.
Tao, can we rely on mirror->lock to provide atomicity here instead?
Cheers

yes, we can. It is already under mirror->lock. So we just need to open
code xchg/cmpxchg(). I'll send a patch to fix it.
