2014-07-21KVM: s390: move vcpu wakeup code to a central pointDavid Hildenbrand
Let's move the vcpu wakeup code to a central point. We should set the vcpu->preempted flag only if the target is actually sleeping and before the real wakeup happens. Otherwise the preempted flag might be set, when not necessary. This may result in immediate reschedules after schedule() in some scenarios. The wakeup code doesn't require the local_int.lock to be held.

2014-07-21KVM: s390: cleanup handle_wait by reusing kvm_vcpu_blockDavid Hildenbrand
This patch cleans up the code in handle_wait by reusing the common code function kvm_vcpu_block. signal_pending(), kvm_cpu_has_pending_timer() and kvm_arch_vcpu_runnable() are sufficient for checking if we need to wake-up that VCPU. kvm_vcpu_block uses these functions, so no checks are lost. The flag "timer_due" can be removed - kvm_cpu_has_pending_timer() tests whether the timer is pending, thus the vcpu is correctly woken up.

2014-07-21batman-adv: fix TT VLAN inconsistency on VLAN re-addAntonio Quartulli
When a VLAN interface (on top of batX) is removed and re-added within a short timeframe TT does not have enough time to properly cleanup. This creates an internal TT state mismatch as the newly created softif_vlan will be initialized from scratch with a TT client count of zero (even if TT entries for this VLAN still exist). The resulting TT messages are bogus due to the counter / tt client listing mismatch, thus creating inconsistencies on every node in the network To fix this issue destroy_vlan() has to not free the VLAN object immediately but it has to be kept alive until all the TT entries for this VLAN have been removed. destroy_vlan() still removes the sysfs folder so that the user has the feeling that everything went fine. If the same VLAN is re-added before the old object is free'd, then the latter is resurrected and re-used. Implement such behaviour by increasing the reference counter of a softif_vlan object every time a new local TT entry for such VLAN is created and remove the object from the list only when all the TT entries have been destroyed.

2014-07-20net_sched: avoid generating same handle for u32 filtersCong Wang
When kernel generates a handle for a u32 filter, it tries to start from the max in the bucket. So when we have a filter with the max (fff) handle, it will cause kernel always generates the same handle for new filters. This can be shown by the following command: tc qdisc add dev eth0 ingress tc filter add dev eth0 parent ffff: protocol ip pref 770 handle 800::fff u32 match ip protocol 1 0xff tc filter add dev eth0 parent ffff: protocol ip pref 770 u32 match ip protocol 1 0xff ... we will get some u32 filters with same handle: # tc filter show dev eth0 parent ffff: filter protocol ip pref 770 u32 filter protocol ip pref 770 u32 fh 800: ht divisor 1 filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0 match 00010000/00ff0000 at 8 filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0 match 00010000/00ff0000 at 8 filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0 match 00010000/00ff0000 at 8 filter protocol ip pref 770 u32 fh 800::fff order 4095 key ht 800 bkt 0 match 00010000/00ff0000 at 8 handles should be unique. This patch fixes it by looking up a bitmap, so that can guarantee the handle is as unique as possible. For compatibility, we still start from 0x800. Cc: "David S.

2014-07-19Btrfs: fix abnormal long waiting in fsyncLiu Bo
xfstests generic/127 detected this problem. With commit 7fc34a62ca4434a79c68e23e70ed26111b7a4cf8, now fsync will only flush data within the passed range. This is the cause of the above problem, -- btrfs's fsync has a stage called 'sync log' which will wait for all the ordered extents it've recorded to finish. In xfstests/generic/127, with mixed operations such as truncate, fallocate, punch hole, and mapwrite, we get some pre-allocated extents, and mapwrite will mmap, and then msync. And I find that msync will wait for quite a long time (about 20s in my case), thanks to ftrace, it turns out that the previous fallocate calls 'btrfs_wait_ordered_range()' to flush dirty pages, but as the range of dirty pages may be larger than 'btrfs_wait_ordered_range()' wants, there can be some ordered extents created but not getting corresponding pages flushed, then they're left in memory until we fsync which runs into the stage 'sync log', and fsync will just wait for the system writeback thread to flush those pages and get ordered extents finished, so the latency is inevitable. This adds a flush similar to btrfs_start_ordered_extent() in btrfs_wait_logged_extents() to fix that.
