81d3def3c2 doc: Describe mClock's use within Ceph in great detail. 
It seems many are initially unclear as to how the current
implementations of mclock op queues work, so we need to document it to
avoid confusion.

48308954cb Clarify journal size based on filestore max sync 
The docs had the recommended journal size based on the option
"filestore min sync interval" when it should have been
"filestore max sync interval".

While in there, fix a couple of typos -- multiple when it should
be multiply, and a missing word.  Change "Should at least twice"
to "Should be at least twice..."
