+Subject: Revert "block: freeze the queue earlier in del_gendisk"
+
+From: Christoph Hellwig <hch@lst.de>
+
+commit 4c66a326b5ab784cddd72de07ac5b6210e9e1b06 upstream.
+
+This reverts commit a09b314005f3a0956ebf56e01b3b80339df577cc.
+
+Dusty Mabe reported consistent hang during CoreOS shutdown with a MD
+RAID1 setup.  Although apparently similar hangs happened before,
+and this patch most likely is not the root cause it made it much
+more severe.  Revert it until we can figure out what is going on
+with the md driver.
