[arty] 44180: Make AVL generic table correctly report that it's inserted a new node, and fix non-new insert slightly. If we unstub filelock and oplock, we can cmd line browse an ext3 fs with matt wu's ext2fsd (win2k build, from the website). It throws STATUS_IN_PAGE_ERROR back up to explorer while browsing, probably because of stubbed functions, but doesn't bugcheck. Implementing just a bit more fsrtl will complete it.
