From: Omar Sandoval <osandov@xxxxxx> Hi, Jens, This series has some fixes and enhancements for blk-mq: - Patch 1 is a cleanup in preparation for the rest of the series - Patch 2 is a fix necessary for patch 4 when scheduling is enabled, making sure we bring up new hardware queues with scheduler tags - Patch 3 makes error handling in elevator_switch() more robust, making us fall back to none like you recommended last time - Patch 4 is the remap fix from last week - Patch 5 is an extension of patch 2 for multiqueue schedulers that allocate per-hctx data. Nothing in-tree needs it, but Kyber will. Let me know if you'd prefer deferring this to 4.12 or want to apply 1-4 for 4.11. These are based on block/for-next, so the latter might require a respin. Thanks!
