273d29fa4beb3954c970b6377a2aa6ee442b1430 is the first bad commit commit 273d29fa4beb3954c970b6377a2aa6ee442b1430 Author: Christoph Hellwig <hch@lst.de> Date: Tue Nov 1 16:00:47 2022 +0100
blk-mq: move the srcu_struct used for quiescing to the tagset [ Upstream commit 80bd4a7aab4c9ce59bf5e35fdf52aa23d8a3c9f5 ] All I/O submissions have fairly similar latencies, and a tagset-wide quiesce is a fairly common operation.
