Revision d5ed3a4af77b851b6271ad3d9abc4c57fa3ce0f5 authored by Jan Kara on 19 August 2010, 21:13:33 UTC, committed by Linus Torvalds on 20 August 2010, 16:34:55 UTC
When radix_tree_maxindex() is ~0UL, it can happen that scanning overflows index and tree traversal code goes astray reading memory until it hits unreadable memory. Check for overflow and exit in that case.
