Subject: [PATCH v3 20/34] dmaengine: xilinx-dpdma: kill vchan BH on remove
Date: Mon, 10 Aug 2026 11:09:21 -0700	[thread overview]
Message-ID: <7185ee59e7bc0451f9ebb19178d3f76edee65658.1786384169.git.allen.lkml@gmail.com> (raw)
In-Reply-To: <cover.1786384168.git.allen.lkml@gmail.com>

virt-dma now dispatches completion callbacks through per-channel BH
work. Cancel that work when removing a channel, while retaining the
driver's separate error-handling tasklet.
