[PATCH net-next v5 06/10] dmaengine: xilinx_dma: Use tasklet_hi_schedule for timing critical usecase

From: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com>
Date: 2023-08-07 05:53:27
Also in: dmaengine, linux-devicetree, lkml, netdev
Subsystem: dma generic offload engine subsystem, the rest · Maintainers: Vinod Koul, Linus Torvalds

Schedule tasklet with high priority to ensure that callback processing
is prioritized. It improves throughput for netdev dma clients.
