Pull documentation updates from Jon Corbet:
 "A relatively boring cycle in the docs tree.  There's a few kernel-doc
  fixes and various document tweaks.

  One patch reaches out of the documentation subtree to fix a comment in
  init/do_mounts_rd.c.  There didn't seem to be anybody more appropriate
  to take that one, so I accepted it"

Default value for this parameter is 8ms.
latency
-------
This parameter is used to enable/disable the latency mode of the CFQ
scheduler. If latency mode (called low_latency) is enabled, CFQ tries
to recompute the slice time for each process based on the target_latency set
for the system. This favors fairness over throughput. Disabling low
latency (setting it to 0) ignores target latency, allowing each process in the
system to get a full time slice.
