Make it more clear that update_peer_seq() is supposed to wake up the seq_wait queue whenever the sequence number changes. Signed-off-by:

Before submitting a new local write request, wait for any conflicting local or remote requests to complete. We could assume that the new request occurred first and that the conflicting requests overwrote it (and therefore discard the new reques), but we know for sure that the new request occurred after the conflicting requests and so this behavior would we weird. We would also end up with the wrong result if the new request is not fully contained within the conflicting requests. Signed-off-by:

Nothing in this function accesses mdev->tconn->net_conf, so there is no need for get_net_conf() / put_net_conf() anymore. Signed-off-by:

Instead of keeping a separate tree for local and remote write requests for finding requests and for conflict detection, use the same tree for both purposes. Introduce a flag to allow distinguishing the two possible types of entries in this tree. Signed-off-by:

Now drbd communication with protocol 100 actually works. Replaced the remaining p_header80 with p_header where we no longer know which header it is. In the places where p_header80 is still in use, it is on purpose, because we know that it is an old style header there. Signed-off-by:

The new header layout will only be used if the peer supports it of course. For the first packet and the handshake packet the old (h80) layout is used for compatibility reasons. Signed-off-by:

The open_cnt check is an open-coded D_ASSERT() check. In case the data.work queue is not empty, it does not really help to know which drbd_work elements remained on that list: they will be freed immediately afterwards, anyway. Signed-off-by:

We do not do collision detection for read requests, but we still need to look up the request objects when we receive a package over the network. Using the same data structure for read and write requests results in simpler code once the tl_hash and app_reads_hash tables are removed. Signed-off-by:
