Eric Dumazet ea44828c41 dma-debug: add a schedule point in debug_dma_dump_mappings() ... [ Upstream commit 9ff6aa027d ] debug_dma_dump_mappings() can take a lot of cpu cycles : lpk43:/# time wc -l /sys/kernel/debug/dma-api/dump 163435 /sys/kernel/debug/dma-api/dump real 0m0.463s user 0m0.003s sys 0m0.459s Let's add a cond_resched() to avoid holding cpu for too long.
