[PATCH tip/core/rcu 11/14] documentation: Transitivity is not cumulativity

From: Paul E. McKenney
Date: Wed Feb 24 2016 - 00:09:38 EST


The "transitivity" section mentions cumulativity in a potentially
confusing way. Contrary to the current wording, cumulativity is
not transitivity, but rather a hardware discipline that can be used
to implement transitivity on ARM and PowerPC CPUs. This commit
therefore deletes the mention of cumulativity.

Transitivity is a deeply intuitive notion about ordering that is not
always provided by real computer systems. The following example
