+Subject: [PATCH] block, bfq: attempt to fix use-after-free which affects SLUB
+ behavior (3.3.0 to 3.8.0)
+
+It may happen that a call to bfq_del_bfqq_busy() puts the last
+reference taken on a queue and frees it. Subsequent accesses to that
+same queue would result in a use-after-free. Make sure that a queue
+that has just been deleted from busy is no more touched.

+
+It may happen that a variable is initialized in a function that is
+called by the function that defined it. Use the uninitialized_var()
+macro in these cases.

+
+    USB: add RESET_RESUME for webcams shown to be quirky
+
+    The new runtime PM code has shown that many webcams suffer
+    from a race condition that may crash them upon resume.
+    Runtime PM is especially prone to show the problem because
+    it retains power to the cameras at all times. However
+    system suspension may also crash the devices and retain
+    power to the devices.
+    The only way to solve this problem without races is in
+    usbcore with the RESET_RESUME quirk.
