| |
Hi Linus, please pull these fixes. I think raid5 is all working nicely again now. I think there is still a race somewhere in starting the recovery thread, but it is minor and I suspect I'll have it nailed soon. Not quite this week though.
Thanks, NeilBrown

md: fix race when unfreezing sync_action (2015-05-28 18:04:45 +1000)
---------------------------------------------------------------- Assorted fixes for new RAID5 stripe-batching functionality.
Unfortunately this functionality was merged a little prematurely. The necessary testing and code review is now complete (or as complete as it can be) and to code passes a variety of tests and looks quite sensible.
Also a fix for some recent locking changes - a race was introduced which causes a reshape request to sometimes fail. No data safety issues.
---------------------------------------------------------------- NeilBrown (10): md/raid5: ensure whole batch is delayed for all required bitmap updates. md/raid5: close race between STRIPE_BIT_DELAY and batching. md/raid5: Ensure a batch member is not handled prematurely. md/raid5: remove condition test from check_break_stripe_batch_list. md/raid5: duplicate some more handle_stripe_clean_event code in break_stripe_batch_list md/raid5: add handle_flags arg to break_stripe_batch_list. md/raid5: be more selective about distributing flags across batch. md/raid5: call break_stripe_batch_list from handle_stripe_clean_event md/raid5: break stripe-batches when the array has failed. md: fix race when unfreezing sync_action
