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.
