Subject: maple_tree: use cached node end in mas_destroy()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1f41ef12abf8538b3d82cdae14c06aa171cb71ce;p=linux.git

maple_tree: use cached node end in mas_destroy()

The node end is set during the walk, so use the resulting end instead of
re-fetching it.
