Subject: [PATCH 0/2] wifi: ipw2x00: drain IRQ tasklets during teardown
Date: Wed, 28 Oct 2026 12:56:00 +0800 [thread overview]
Message-ID: <20261028045602.111668-1-yaojiale02@163.com> (raw)
The ipw2100 and ipw2200 interrupt handlers defer device processing to
tasklets. Their teardown paths free the IRQ, queues, MMIO mappings, and
driver-private state without draining tasklets that may already be queued.
Kill each IRQ tasklet after preventing new IRQ scheduling and before
releasing the resources used by the deferred handler.
