* libceph: flush msgr queue during mon_client shutdownSage Weil2012-06-20
| | | | | | | | | | | | | | | | We need to flush the msgr workqueue during mon_client shutdown to ensure that any work affecting our embedded ceph_connection is finished so that we can be safely destroyed. Previously, we were flushing the work queue after osd_client shutdown and before mon_client shutdown to ensure that any osd connection refs to authorizers are flushed. Remove the redundant flush, and document in the comment that the mon_client flush is needed to cover that case as well.

* libceph: use con get/put ops from osd_clientSage Weil2012-06-20
| | | | | | | | | | | | | | | | | | | | There were a few direct calls to ceph_con_{get,put}() instead of the con ops from osd_client.c. This is a bug since those ops aren't defined to be ceph_con_get/put. This breaks refcounting on the ceph_osd structs that contain the ceph_connections, and could lead to all manner of strangeness. The purpose of the ->get and ->put methods in a ceph connection are to allow the connection to indicate it has a reference to something external to the messaging system, *not* to indicate something external has a reference to the connection.

* libceph: osd_client: don't drop reply reference too earlyAlex Elder2012-06-20
| | | | | | | | | | | In ceph_osdc_release_request(), a reference to the r_reply message is dropped. But just after that, that same message is revoked if it was in use to receive an incoming reply. Reorder these so we are sure we hold a reference until we're actually done with the message.

| * ALSA: hda - Handle open while transitioning to D3.Dylan Reid2012-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

This became an issue recently because struct edac_mc_layer has a size that is not zero modulo eight, so we were taking the correctly-aligned pointer and forcing it to be misaligned.

But in current notifier_chain implementation logic, it doesn't accept same notifier registered twice. If so, it will be wrong when adding/removing the element from the list. For example, on one SandyBridge platform, remove module sb_edac and then trigger one error, it will hit oops because it has no mce decoder registered but related notifier_chain still points to an invalid callback function.

Current handling of IDMAC interrupt sets EVENT_DATA_COMPLETE as well as EVENT_XFER_COMPLETE regardless of DTO rising. This makes the current request finish in tasklet and permits the next request even though current data transfer is still in progress. As a result, sequence is broken and lock-up happens. Setting EVENT_DATA_COMPLETE is not proper after IDMAC interrupt. It should be taken after DTO interrupt is generated.
