Hi all,

this is my spin at sorting out the long lock hold times in
__purge_vmap_area_lazy.  It is based on the patch from Joel sent this
week.  I don't have any good numbers for it, but it survived an
xfstests run on XFS which is a significant vmalloc user.  The
changelogs could still be improved as well, but I'd rather get it
out quickly for feedback and testing.

All patches look great to me, and thanks a lot.

Regards,
Joel
