We need to make sure that hdev->{rx_work,cmd_work,tx_work} which are queued into hdev->workqueue and hdev->{power_on,error_reset} which are queued into hdev->req_workqueue are no longer running by the moment destroy_workqueue(hdev->workqueue); destroy_workqueue(hdev->req_workqueue); are called from hci_release_dev(). Call cancel_work_sync() on these work items from hci_unregister_dev() as soon as hdev->list is removed from hci_dev_list.

[PATCH OLK-6.6 0/2] mm/dynamic_pool: two bugfix about THP and migration
by Liu Shixin 01 Aug '24

01 Aug '24

Recently, we found there are some cases that the dynamic pool is not working as expected and the pages is allocated from buddy system. There are mainly two reason: 1. THP is not supported on dynamic pool, some path is not restricted to allocate THP which the allocation from dynamic pool is failed and fallback to allocate from buddy system. 2. The numa balance will try to migrate the pages coming from dynamic pool and use pages from buddy system instead.
