This the first request for review of drbd-8.4. The complete set has 500 patches. In this first series there are only 118 of these.
The most noticeable change is the support for multiple replicated volumes in a single DRBD connection. Write-ordering is obeyed among all writes in all volumes in a single connection. This feature is really important for users who use DRBD for mirroring over longer distances. (Protocol A).
0001 - 0012 cleanups 0013 - 0026 replace the hash tables of drbd_requests with two interval trees 0027 have a look at the idr_for_each_entry(). Outside of drbd's directory. 0028 - 0035 introduced a new object which represents a DRBD connection; move a view members from the device object to the new conenction object 0036 - 0041 Introduce volume numbers into the protocol 0042 - 0052 cleanups; renames; 0053 Improvements to handling of conflicting writes 0054 - 0060 cleanups; renames; 0061 - 0064 code reorganisation 0065 IO latency bugfix 0066 - 0099 moving members from the device object to the connection object; converting function from the device object to the connection obj 0100 - 0118 work on the state engine to match the new object model
