Actually, it wasn't converting an existing loop; it was adding a new
GFP_NOFAIL to fix a reclaim livelock (commit 84235de394d9775bf).
I agree that in ideal world, we'd get rid of all of these. But
sometimes, the cure can be worse than the disesae, and so the whole
"all callers of GFP_NOFAIL are MUST FIX BUGGGY and the maintainers
should be shamed into fixing it" attitude is one that I find a bit odd
myself.
