Subject: maple_tree: Handle ZERO entry in mt_dump()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=406555dcd189feea7eb8a7d530b522d000590af3;p=users%2Fjedix%2Flinux-maple.git

maple_tree: Handle ZERO entry in mt_dump()

If there is a single ZERO entry in mt->root, this should be printed
as 0-0, not 0-ULONG_MAX.
