commit f1be1788a32e8fa63416ad4518bbd1a85a825c9d Author: Ming Lei Date: Fri Oct 25 08:37:20 2024 +0800 block: model freeze & enter queue as lock for supporting lockdep Recently we got several deadlock report[1][2][3] caused by blk_mq_freeze_queue and blk_enter_queue(). Turns out the two are just like acquiring read/write lock, so model them as read/write lock for supporting lockdep: 1) model q->q_usage_counter as two locks(io and queue lock) - queue lock covers sync with blk_enter_queue() - io lock covers sync with bio_enter_queue() 2) make the lockdep class/key as per-queue: - different subsystem has very different lock use pattern, shared lock class causes false positive easily - freeze_queue degrades to no lock in case that disk state becomes DEAD because bio_enter_queue() won't be blocked any more - freeze_queue degrades to no lock in case that request queue becomes dying because blk_enter_queue() won't be blocked any more 3) model blk_mq_freeze_queue() as acquire_exclusive & try_lock - it is exclusive lock, so dependency with blk_enter_queue() is covered - it is trylock because blk_mq_freeze_queue() are allowed to run concurrently 4) model blk_enter_queue() & bio_enter_queue() as acquire_read() - nested blk_enter_queue() are allowed - dependency with blk_mq_freeze_queue() is covered - blk_queue_exit() is often called from other contexts(such as irq), and it can't be annotated as lock_release(), so simply do it in blk_enter_queue(), this way still covered cases as many as possible With lockdep support, such kind of reports may be reported asap and needn't wait until the real deadlock is triggered. For example, lockdep report can be triggered in the report[3] with this patch applied.
