Okay, I started playing with that. First mkaffs craps out when you hand it a too large partition and stays in an uninterruptible loop for a long time. Might be worth adding some sanity check then. Then affs doesn't really survive fsstress from ltp very well. The first lockdep warning I got is from my implement drop_inode patch but even with that things look quite bad, with both lockdep warnings and lots of 'VFS: brelse: Trying to free free buffer' with following stack trace. Any idea how to proceed with affs?
