[PATCH 01/10] KVM: SVM: Notify nested hypervisor of lost event injections
From: Alexander Graf <agraf(a)suse.de> If event_inj is valid on a #vmexit the host CPU would write the contents to exit_int_info, so the hypervisor knows that the event wasn't injected. We don't do this in nested SVM by now which is a bug and fixed by this patch. Signed-off-by: Alexander Graf <agraf(a)suse.de> ... 7 Oct 2009 10:46

[PATCH 26/45] block: pass the non-rotational queue flag to backing_dev_info
For now only pass the non-rotational bit to the queue's bdi. To support hierarchical dm/md configurations, blk_set_rotational() shall be expanded to make several iterations of the bdi list and call its bdi->rotational_fn to pass the bit up. But that would imply we don's support mixed SSD/HD arrays. CC: Jens A... 7 Oct 2009 04:11

[PATCH 33/45] writeback: sync livelock - introduce wbc.for_sync
The sync() is performed in two stages: the WB_SYNC_NONE sync and the WB_SYNC_ALL sync. It is necessary to tag both stages with wbc.for_sync, so as to prevent either of them being livelocked. The next patch will utilize this flag to do the livelock prevention. CC: Jan Kara <jack(a)suse.cz> Signed-off-by: Wu Feng... 7 Oct 2009 04:11
