[PATCH v3 14/35] maple_tree: Use MAS_BUG_ON() prior to calling mas_meta_gap()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Replace the call to BUG_ON() in mas_meta_gap() with calls before the
function call MAS_BUG_ON() to get more information on error condition.
