2024-03-04dm vdo permassert: audit all of ASSERT to test for VDO_SUCCESSMike Snitzer
Also rename ASSERT to VDO_ASSERT and ASSERT_LOG_ONLY to VDO_ASSERT_LOG_ONLY. But re-introduce ASSERT and ASSERT_LOG_ONLY as a placeholder for the benefit of dm-vdo/indexer. Signed-off-by: Mike Snitzer <snitzer@kernel.org> Signed-off-by: Matthew Sakai <msakai@redhat.com>
2024-02-20dm vdo: add specialized request queueing functionalityMatthew Sakai
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.
