[S390] cio: prevent workqueue deadlock

2009-03-26T14:24:18Z

Subchannel reprobing can block the kslowcrw workqueue indefinitely while waiting for device recognition to finish which is also scheduled to run on kslowcrw. Prevent this deadlock by moving the waiting portion of subchannel reprobing to the cio workqueue. Signed-off-by: Peter Oberparleiter Signed-off-by: Martin Schwidefsky

[S390] cio: device scan oom fallback.

2009-03-26T14:24:14Z

Since some callers rely on for_each_subchannel_staged to not fail, fall back to brute force scanning using get_subchannel_by_schid in case of a oom situation. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

Driver core: implement uevent suppress in kobject

2009-03-24T23:38:26Z

This patch implements uevent suppress in kobject and removes it from struct device, based on the following ideas: 1,Uevent sending should be one attribute of kobject, so suppressing it in kobject layer is more natural than in device layer. By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future. [This version is against the latest driver-core patch set of Greg,please ignore the last version.] Signed-off-by: Ming Lei Signed-off-by: Greg Kroah-Hartman

[S390] cio: introduce cio_commit_config

2008-12-25T12:39:10Z

To change the configuration of a subchannel we alter the modifiable bits of the subchannel's schib field and issue a modify subchannel. There can be the case that not all changes were applied -or worse- quietly overwritten by the hardware. With the next store subchannel we obtain the current state of the hardware but lose our target configuration. With this patch we introduce a subchannel_config structure which contains the target subchannel configuration. Additionally the msch wrapper cio_modify is replaced with cio_commit_config which copies the desired changes to a temporary schib. msch is then called with the temporary schib. This schib is only written back to the subchannel if all changes were applied. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] bus_id -> dev_set_name() changes

2008-10-10T19:33:50Z

Convert most s390 users setting bus_id to dev_set_name(). css and ccw busses are deferred since they need some special treatment. Signed-off-by: Cornelia Huck Signed-off-by: Greg Kroah-Hartman Signed-off-by: Martin Schwidefsky
