[Bug 644481] Re: 95-kpartx.rules uses invalid -Q argument to modprobe(8)

[Serge Hallyn]

** Description changed:

  Binary package hint: multipath-tools
  
  95-kpartx.rules calls modprobe(8) with the invalid -Q argument. I'm
  guessing it wants -q, for quiet?
  
  --
  # Always attempt to load dm-multipath. This way we can get rid of the
  # init script.
  ACTION=="add|change", SUBSYSTEM=="block", \
-      RUN+="/sbin/modprobe -Qba dm-multipath"
+      RUN+="/sbin/modprobe -Qba dm-multipath"

+ 
+ SRU Justification:
+ 1. Impact: multipath fails because modprobe doesn't load the needed modules
+ 2. How bug addressed: the udev rule calling multipath is fixed to not use a wrong argument
+ 3. Patch: see comment #3
+ 4. Test case: dont' have dm-multipath in /etc/modules.  95-kpartx.rules won't load it.
+ 5. Regression potential: none.
