This is v3 of patch/series. I have spun off a new patch for tag allocation refactoring.
Details are in commit messages.
Changes since v2: - Spin off separate patch for tag allocation refactoring - Combine sched shared sbitmap code into a single function
Changes since v1: - Embed sbitmaps in request_queue struct - Relocate IO sched functions to blk-mq-sched.c - Fix error path code
Please retest, thanks! For some reason I could not recreate the original issue, but I am using qemu...
