-commit 868a01e894f6abd33a98457a7ee4c1aa7e1eb2fe
-Author: Artur Paszkiewicz <artur.paszkiewicz@intel.com>
-Date:   Tue May 9 11:21:25 2017 +0200

-    Don't rely on searching for "/block" in sysfs path for detecting partitions
-    
-    It is simpler and more reliable to check for a "partition" file in the
-    device's directory (supported since kernel 2.6.28). The previous
-    approach would fail for nvme devices because their device path looks
-    like this:
-    /sys/devices/pci0000:00/0000:00:0c.0/nvme/nvme0/nvme0n1
-    
-    Fixes: b30173ec8c05 ("* fix off-normal-failure block dev status loop * remove unused raid->slave_list member * support md raid on block device partitions")
