This is a follow up to https://lkml.kernel.org/r/20201102181238.GA17806@xxxxxxxxxxxxx where I *think* we agreed to audit driver which complete their blk request from process context and then let them complete the request directly instead going through ksoftirqd. This series converts a part from the MMC layer which completes the requests from kworker/ preemptible context. It was verified with sdhci-pci device under normal usage. It also converts the usb-storage driver which is slightly complicated since it goes through the SCSI layer. Sebastian
