Pan Bian 5ee5fa61d0 hfs: do not free node before using ... [ Upstream commit ce96a407ad ] hfs_bmap_free() frees the node via hfs_bnode_put(node). However, it then reads node->this when dumping error message on an error path, which may result in a use-after-free bug. This patch frees the node only when it is never again used.
