The following commit has been merged in the master branch: commit dec05074b1a322f5fbbe3f81bc438a75bfec3c34 Author: Antonio Quartulli <ordex(a)autistici.org> Date: Sat Nov 10 11:00:32 2012 +0100 batman-adv: Initialize lockdep class keys for hashes Different hashes have the same class key because they get initialised with the same one. For this reason lockdep can create false warning when they are used recursively. Re-initialise the key for each hash after the invocation to hash_new() to avoid this problem.
