Andrew, this is on top of Alexandre Ghiti's "hugetlb: allow to free gigantic
pages regardless of the configuration" patch.  Both patches modify
__nr_hugepages_store_common().  Alex's patch is going to change slightly
in this area.
OK, thanks, I missed that.  Are the changes significant?

No, changes should be minor.  IIRC, just checking for a condition in an
error path.
I will send the v5 of this patch tomorrow, I was waiting for architecture
maintainer remarks. I still miss sh, but I'm confident on this change.

Alex
