2010-02-24virtio: Fix scheduling while atomic in virtio_balloon statsAdam Litke
This is a fix for my earlier patch: "virtio: Add memory statistics reporting to the balloon driver (V4)". I discovered that all_vm_events() can sleep and therefore stats collection cannot be done in interrupt context. One solution is to handle the interrupt by noting that stats need to be collected and waking the existing vballoon kthread which will complete the work via stats_handle_request(). Rusty, is this a saner way of doing business? There is one issue that I would like a broader opinion on. In stats_request, I update vb->need_stats_update and then wake up the kthread. The kthread uses vb->need_stats_update as a condition variable. Do I need a memory barrier between the update and wake_up to ensure that my kthread sees the correct value? My testing suggests that it is not needed but I would like some confirmation from the experts.

2010-02-24virtio: Add memory statistics reporting to the balloon driver (V4)Adam Litke
Changes since V3: - Do not do endian conversions as they will be done in the host - Report stats that reference a quantity of memory in bytes - Minor coding style updates Changes since V2: - Increase stat field size to 64 bits - Report all sizes in kb (not pages) - Drop anon_pages stat and fix endianness conversion Changes since V1: - Use a virtqueue instead of the device config space When using ballooning to manage overcommitted memory on a host, a system for guests to communicate their memory usage to the host can provide information that will minimize the impact of ballooning on the guests. The current method employs a daemon running in each guest that communicates memory statistics to a host daemon at a specified time interval. The host daemon aggregates this information and inflates and/or deflates balloons according to the level of host memory pressure. This approach is effective but overly complex since a daemon must be installed inside each guest and coordinated to communicate with the host. A simpler approach is to collect memory statistics in the virtio balloon driver and communicate them directly to the hypervisor. This patch enables the guest-side support by adding stats collection and reporting to the virtio balloon driver.

2010-02-22i915 / PM: Fix hibernate regression caused by suspend/resume splittingRafael J. Wysocki
Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.

2010-02-20Input: polldev can cause crash in case when polling disabledSamu Onkalo
When polled input device is opened and closed and there are no other users of polled device, the workqueue is created and destroyed in every open / close operation. It is probable that at some point dynamic allocation of internal parts of the workqueue cause changes to the workqueue. When a work is queued to the workqueue the work struct contains pointers to the workqueue data. If the workqueue has been changed and the work has never been queued to the new workqueue, work-struct contains pointers to the non-existing workqueue. This will cause crash at the work cancellation during device close since cancellation of a work assumes that the workqueue exists. To prevent that, work struct is cleaned up at device close. This keeps work struct clean for the next use. Signed-off-by: Samu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-02-17[SCSI] fcoe: Only rmmod fcoe.ko if there are no active connectionsRob Love
Currently we're gracefully tearing down each active connection when fcoe.ko is removed. We shouldn't allow the user to destroy connections by removing the module. We should force the user to destroy each connection and then the module can be removed. This patch makes it so a refrerence count on the module is taken each time a fcoe_interface is created. The reference count is dropped when the fcoe_interface is destroyed. This makes it so that module_exit() doesn't get called unless all fcoe_interfaces have been destroyed. This patch leaves the removal of interfaces in the module_exit routine so that if the user does a 'rmmod -f' we'll clean everything up before removing the module. The module_put line was put before the out_putdev goto line because we should only be decrementing the reference count if a fcoe_interface is actually destroyed. If we can't find the netdev or the fcoe_interface then it's assumed that something else has destroyed the fcoe_interface and it would have decremented the reference count at that time.

2010-02-17[SCSI] libfcoe: Send port LKA every FIP_VN_KA_PERIOD secs.Bhanu Prakash Gollapudi
libfcoe module doesnt send port keep alive every FIP_VN_KA_PERIOD due to improper assignment of timeout value. Update the port_ka_time appropriately by incrementing it by FIP_VN_KA_PERIOD in fcoe_ctlr_timeout(), so that the link_work is scheduled to send the port LKA.

2010-02-17[SCSI] libfc: Don't assume response request present.Hugh Daschbach
Fix NULL pointer dereference crash occurs in fc_lport_bsg_request() for bsg requests that do not contain a response request. Specifically, FC_BSG_HST_ADD_RPORT and FC_BSG_HST_DEL_RPORT bsg requests are not guaranteed to include a response request.

2010-02-17[SCSI] libfc: Fix e_d_tov ns -> ms scaling factor in PLOGI response.Hugh Daschbach
Both PLOGI and RTV response processing conditionally scale e_d_tov, but use different scaling factors. The scaling factor is correct in RTV response processing. Bring PLOGI e_d_tov scaling in line with RTV common service parameter inspection.

2010-02-17[SCSI] libfc: call ddp setup for only FCP reads to avoid accessing junk fsp ↵Vasu Dev
pointer Adds check to call fc_fcp_ddp_setup for only FCP read cmds to avoid accessing junk fsp pointer at least in ESX since non FCP frame had junk fsp value, though fsp is implicitly initialized to null by __alloc_skb but with this patch no more relying on fsp initialized to null value and hitting junk fsp ptr access. Removes fsp pointer checking in fc_fcp_ddp_setup as this is not needed any more since its only caller for FCP read will always have a valid fsp.
