Subject: maple_tree: mas_start() reset depth on dead node
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=52cf1ccaf6a0266074309eb76821c6568360b2ba;p=users%2Fjedix%2Flinux-maple.git

maple_tree: mas_start() reset depth on dead node

When a dead node is detected, the depth has already been set to 1 so
reset it to 0.
