Subject: maple_tree: use MAS_BUG_ON() in mas_set_height()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5950ada963a6e26f318e54f873a4cc5769c1a3da;p=linux.git

maple_tree: use MAS_BUG_ON() in mas_set_height()

Use MAS_BUG_ON() instead of MT_BUG_ON() to get the maple state
information.  In the unlikely event of a tree height of > 31, try to
increase the probability of useful information being logged.
