Analyze and fix the following issue in the Linux kernel code: ocfs2: add OCFS2_INODE_SKIP_ORPHAN_DIR flag and honor it in the inode wipe code
Problem Details: Currently in the error path of ocfs2_symlink and ocfs2_mknod, we just call iput with the inode we failed with, but the inode wipe code will complain because we don't add the inode to orphan dir. One solution would be to lock the orphan dir during the entire transaction, but that's too heavy for a rare ...

Analyze and fix the following issue in the Linux kernel code: ipv6: Fix tcp_v6_send_response transport header setting.
Problem Details: My recent patch to remove the open-coded checksum sequence in tcp_v6_send_response broke it as we did not set the transport header pointer on the new packet. Actually, there is code there trying to set the transport header properly, but it sets it for the wrong skb ('skb' instead of 'buff'). This bug...
