s390/css: stop stsch loop after cc 3

2012-10-18T15:50:08Z

Receiving cc=3 from store subchannel means 2 things: * the subchannel is not provided * there are no further subchannels in this subchannel set With this patch we abort the store subchannel loop after cc=3 (or an exception) and clear the subsequent bits in the subchannel id set.

[S390] hibernate: directly trigger subchannel evaluation

2011-12-01T12:32:17Z

Using the generic css_schedule_eval to evaluate subchannels while resuming from hibernation is very slow when used with many devices. Provide a new evaluation trigger which exploits css_sched_sch_todo and use this in the resume callback for ccw devices. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

2010-10-25T14:10:18Z

Update the channel path descriptors after hibernation. This is done unlocked, since we are the only active task at this time.
