[PATCH] the ac->ac_allow_chain_relink=0 won't disable group relink
From: "Xiaowei.Hu" <xiaowei.hu at oracle.com>
ocfs2_block_group_alloc_discontig() disables chain relink by setting
ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple
cluster groups. It doesn't keep the credits for all chain relink,but
ocfs2_claim_suballoc_bits overrides this in this call trace:
ocfs2_block_group_claim_bits()->ocfs2_claim_clusters()...
