And the task_work can't be run exactly because the task is waiting in the kernel, so we'll never make any progress. One example of that is registering an eventfd and queueing io_uring work, and then the task goes and waits in eventfd read with the expectation that it'll get woken (and read an event) when the io_uring request completes. The io_uring request is finished through task_work, which won't get run while the task is looping in eventfd read" * tag 'io_uring-5.8-2020-07-01' of git://git.kernel.dk/linux-block: io_uring: use signal based task_work running task_work: teach task_work_add() to do signal_wake_up() 2020-06-30T21:58:27+00:00 Mika Westerberg mika.westerberg@linux.intel.com 2020-06-22T16:12:48+00:00 urn:sha1:5396956cc7c6874180c9bfc1ceceb02b739a6a87 Commit 6ae72bfa656e ("PCI: Unify pcie_find_root_port() and pci_find_pcie_root_port()") broke acpi_pci_bridge_d3() because calling pcie_find_root_port() on a Root Port returned NULL when it should return the Root Port, which in turn broke power management of PCIe hierarchies. Rework pcie_find_root_port() so it returns its argument when it is already a Root Port.

The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to avoid the race with recalc_sigpending(), so the patch also adds the new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK. TODO: once this patch is merged we need to change all current users of task_work_add(notify = true) to use TWA_RESUME.
