2013-06-14netiucv: Hold rtnl between name allocation and device registration.Benjamin Poirier1-1/+5

2013-05-31s390/dasd: fix handling of gone pathsStefan Weinhuber1-2/+10
When a path is gone and dasd_generic_path_event is called with a PE_PATH_GONE event, we must assume that any I/O request on that subchannel is still running. This is unlike the dasd_generic_notify handler and the CIO_NO_PATH event, which implies that the subchannel has been cleared. If dasd_generic_path_event finds that the path has been the last usable path, it must not call dasd_generic_last_path_gone (which would reset the state of running requests), but just set the DASD_STOPPED_DC_WAIT bit.

2013-04-26s390/memory hotplug: prevent offline of active memory incrementsHeiko Carstens1-1/+3
In case a machine supports memory hotplug all active memory increments present at IPL time have been initialized with a "usecount" of 1. This is wrong if the memory increment size is larger than the memory section size of the memory hotplug code. If that is the case the usecount must be initialized with the number of memory sections that fit into one memory increment. Otherwise it is possible to put a memory increment into standby state even if there are still active sections. Afterwards addressing exceptions might happen which cause the kernel to panic. However even worse, if a memory increment was put into standby state and afterwards into active state again, it's contents would have been zeroed, leading to memory corruption. This was only an issue for machines that support standby memory and have at least 256GB memory. This is broken since commit fdb1bb15 "[S390] sclp/memory hotplug: fix initial usecount of increments".

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

2013-04-17s390/cio: fix early init counter usageSebastian Ott2-9/+6
Via ccw_device_init_count we keep track of how many devices are in asynchronous device recognition/initialization. For early devices this variable was not only used prior to its initialization but used incorrectly (incremented but never decremented). Fix this by using static initialization for this variable (and friends), make them visible to device.c only, and decrement the counter after recognition of early devices is finished.
