Subject: [PATCH 0/6] blk-mq: update_nr_hw_queues related improvement & bugfix
Date: Mon, 28 Feb 2022 17:04:24 +0800 [thread overview]
Message-ID: <20220228090430.1064267-1-ming.lei@redhat.com> (raw)
Hi,
The 1st patch figures out correct numa node for each kind of hw queue.
The 2nd patch simplifies reallocation of q->queue_hw_ctx a bit.
The 3rd patch re-configures poll capability after queue map is changed.
The 4th patch changes mtip32xx to avoid to refer to q->queue_hw_ctx
directly.
The 5th & 6th patches fix use-after-free on q->queue_hw_ctx.
Ming Lei (6):
blk-mq: figure out correct numa node for hw queue
blk-mq: simplify reallocation of hw ctxs a bit
blk-mq: re-config poll after queue map is changed
block: mtip32xx: don't touch q->queue_hw_ctx
blk-mq: add helper of blk_mq_get_hctx to retrieve hctx via its index
blk-mq: manage hctx map via xarray
