Hi
I found several issues during NVMe rescan/reset/remove with IO on 4.10.0-rc8, could you help check it, thanks.
Steps I used:
#fio -filename=/dev/nvme0n1p1 -iodepth=1 -thread -rw=randwrite -ioengine=psync -bssplit=5k/10:9k/10:13k/10:17k/10:21k/10:25k/10:29k/10:33k/10:37k/10:41k/10 -bs_unaligned -runtime=1200 -size=-group_reporting -name=mytest -numjobs=60 &
#lspci | grep -i nvme
84:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller 172X (rev 01)
#sleep 35
#echo 1 > /sys/bus/pci/devices/0000:84:00.0/rescan
#echo 1 > /sys/bus/pci/devices/0000:84:00.0/reset
#echo 1 > /sys/bus/pci/devices/0000:84:00.0/remove
