The issue is caused when the value of lp becomes greater than CTLTREESIZE which is the max size of stree. Adding a simple check solves this issue. Dave: As the function returns a void, good error handling would require a more intrusive code reorganization, so I modified Osama's patch at use WARN_ON_ONCE for lack of a cleaner option. The patch is tested via syzbot.
