| * [S390] dasd: tolerate devices that have no feature codesStefan Weinhuber2009-09-221-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The DASD device driver reads the feature codes of a device during device initialization. These codes are later used to determine the availability of advanced features like PAV or High Performance FICON. Some very old devices do not support the command to read feature codes and the initialization routine fails. As the feature codes are not necessary for basic DASD operations, we can support such devices by just ignoring missing feature codes.

| * [S390] zcrypt: Do not add/remove devices in s/r callbacksFelix Beck2009-09-221-11/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices are no longer removed or added in the suspend and resume callbacks. Instead they are marked unregistered in suspend. In the resume callback the ap_scan_bus method is scheduled. The bus scan function will remove the old device and add new ones. This way all the device handling will be done in only one function. Additionaly the case where the domain might change during suspend/resume is caught. In that case the devices qid needs to re-calculated in order of having it found by the scan method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, zfcp allocated all resources required for FCP adapters/subchannels when the device was discovered in the ccw_probe callback. If there are lots of unused FCP subchannels attached to a system, this is a waste of resources. To alleviate this, defer the resource allocation to the first call to ccw_set_online. To avoid disruptions during possible following calls to ccw_set_offline and then ccw_set_online, keep the adapter resources until the device is finally being removed via ccw_remove. While doing this, also manage the zfcp erp thread together with all other adapter resources in zfcp_adapter_enqueue/dequeue.

This introduces dependences between the definitions in zfcp_def.h and zfcp_dbf.h. Move all debug related data structures to a new data structure to break those dependencies and manage the debug data in zfcp_dbf.[hc].

| * [SCSI] zfcp: invalid usage after free of port resourcesSwen Schillig2009-09-052-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | In certain error scenarios ports, rports are getting attached, validated and removed from the systems environment. Depending on the layer this occurs asynchronously. This patch fixes the few races which existed and ensures all references and cross references are cleared at the time they're invalid. In addition fc transports actions are only scheduled when required.

Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If nothing has been written into the qeth sysfs-attribute layer2, its value is "-1" meaning "not yet defined". But the value is displayed as "1" meaning "layer2 selected". The patch changes the reading of this "-1"-value to "-1" to make clear the layer2-attribute has not yet been defined.
