> A: cd /mnt/a/b > B: mv /mnt/a/b /mnt > B: mv /mnt/a /mnt/b > A: cd a I think with this it's possible (though not easy) to deadlock NFS: A: cd /mnt/a; sleep 10000 & cd b B: mv /mnt/a/b /mnt/b B: mv /mnt/a /mnt/b/a A: mv /proc/`pidof sleep`/cwd/x x & rmdir /mnt/b/a The mv will first lock a, then b (since it's CWD is /mnt/a/b, so parents in the rename will be /mnt/a and /mnt/a/b), the rmdir will first lock b, then a. So you have a perfect abba deadlock.
