Freezing tasks via the cgroup freezer causes the load average to climb because the freezer's current implementation puts frozen tasks in uninterruptible sleep (D state). Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

Impact: circular locking bugfix The various implemetnations and proposed implemetnations of work_on_cpu() are vulnerable to various deadlocks because they all used queues of some form. Unrelated pieces of kernel code thus gained dependencies wherein if one work_on_cpu() caller holds a lock which some other work_on_cpu() callback also takes, the kernel could rarely deadlock. Fix this by creating a short-lived kernel thread for each work_on_cpu() invokation. This is not terribly fast, but the only current caller of work_on_cpu() is pci_call_probe(). It would be nice to find some other way of doing the node-local allocations in the PCI probe code so that we can zap work_on_cpu() altogether. The code there is rather nasty. I can't think of anything simple at this time... Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

由 Mikulas Patocka 提交于
If the thread calling dm_kcopyd_copy is delayed due to scheduling inside split_job/segment_complete and the subjobs complete before the loop in split_job completes, the kcopyd callback could be invoked from the thread that called dm_kcopyd_copy instead of the kcopyd workqueue. dm_kcopyd_copy -> split_job -> segment_complete -> job->fn() Snapshots depend on the fact that callbacks are called from the singlethreaded kcopyd workqueue and expect that there is no racing between individual callbacks. The racing between callbacks can lead to corruption of exception store and it can also mean that exception store callbacks are called twice for the same exception - a likely reason for crashes reported inside pending_complete() / remove_exception(). This patch fixes two problems: 1. job->fn being called from the thread that submitted the job (see above). - Fix: hand over the completion callback to the kcopyd thread. 2. job->fn(read_err, write_err, job->context); in segment_complete reports the error of the last subjob, not the union of all errors. - Fix: pass job->write_err to the callback to report all error bits (it is done already in run_complete_job) Cc: stable@kernel.org Signed-off-by: NMikulas Patocka <mpatocka@redhat.com> Signed-off-by: NAlasdair G Kergon <agk@redhat.com>

由 Mikulas Patocka 提交于
Barriers are submitted to a worker thread that issues them in-order. The thread is modified so that when it sees a barrier request it waits for all pending IO before the request then submits the barrier and waits for it. (We must wait, otherwise it could be intermixed with following requests.) Errors from the barrier request are recorded in a per-device barrier_error variable. There may be only one barrier request in progress at once. For now, the barrier request is converted to a non-barrier request when sending it to the underlying device. This patch guarantees correct barrier behavior if the underlying device doesn't perform write-back caching. The same requirement existed before barriers were supported in dm. Bottom layer barrier support (sending barriers by target drivers) and handling devices with write-back caches will be done in further patches.

Remove queue_io return value and a loop in dm_request. IO may be submitted to a worker thread with queue_io(). queue_io() sets DMF_QUEUE_IO_TO_THREAD so that all further IO is queued for the thread. When the thread finishes its work, it clears DMF_QUEUE_IO_TO_THREAD and from this point on, requests are submitted from dm_request again. This will be used for processing barriers. Remove the loop in dm_request. queue_io() can submit I/Os to the worker thread even if DMF_QUEUE_IO_TO_THREAD was not set.

One-liner: capsh --print is broken without this patch. In certain cases, cap_prctl returns error > 0 for success. However, the 'no_change' label was always setting error to 0. As a result, for example, 'prctl(CAP_BSET_READ, N)' would always return 0. It should return 1 if a process has N in its bounding set (as by default it does). I'm keeping the no_change label even though it's now functionally the same as 'error'.

This patch removes the sysfs entry num_vfs which was added to support enabling pci virtual functions for 82576. To prevent VFs from loading automatically a module parameter "max_vfs" was added so that the number of VFs per PF can be limited. This is especially useful when 4 or more 82576 ports are on the system because otherwise to load all VFs would result in 8 interface per physical port.

This adds an igbvf driver to handle virtual functions provided by the igb driver when SR-IOV has been enabled. A virtual function is a lightweight pci-e function that supports a single queue and shares resources with the 82576 physical function contained within the igb driver. To spawn virtual functions from the igb driver all that is needed is to enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that supports SR-IOV in the BIOS. The virtual functions will appear after the interface is loaded.
