Subject: Re: [PATCH 2/2] osfs2: Fix kernel BUG in ocfs2_write_cluster

Yes, you are absolutely right, __ocfs2_claim_clusters indeed
allocates 0 as the bit_off, looking into this I believe the
problem is triggered due to ocfs2_search_chain called by
ocfs2_claim_suballoc_bits, what do you think would be the best
approach to solve this issue, what function I be looking for,
any insights will be highly appreciated.

Thanks!
