From de0328d3a253a339be14a80fe2a0256ec26867da Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 8 Mar 2022 15:32:17 +0800 Subject: [PATCH] block: mtip32xx: don't touch q->queue_hw_ctx q->queue_hw_ctx is really one blk-mq internal structure for retrieving hctx via its index, not supposed to be used by drivers. Meantime drivers can get the tags structure easily from tagset.
