dm vdo: remove redundant TYPE argument from vdo_allocate macro

2026-03-02T16:03:28+00:00

We can infer the type needed from the supplied pointer argument. A couple invocation sites needed fixing to supply the proper type of pointer. Use overflow.h's size_mul, and we can remove the __vdo_do_allocation wrapper which did the same overflow check. Signed-off-by: Ken Raeburn Signed-off-by: Mikulas Patocka

vdo: omit need_resched() before cond_resched()

2025-07-31T13:39:55+00:00

There's no need to call need_resched() because cond_resched() will do nothing if need_resched() returns false. Reviewed-by: Matthew Sakai Signed-off-by: Mikulas Patocka

dm vdo: add specialized request queueing functionality

2024-02-20T18:43:13+00:00

This patch adds funnel_queue, a mostly lock-free multi-producer, single-consumer queue. It also adds the request queue used by the dm-vdo deduplication index, and the work_queue used by the dm-vdo data store. Both of these are built on top of funnel queue and are intended to support the dispatching of many short-running tasks. The work_queue also supports priorities. Finally, this patch adds vdo_completion, the structure which is enqueued on work_queues.
