From e73c14ebc36bf2ba28784ff05133283003aaafdb Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 28 Jun 2016 19:52:01 -0700 Subject: rcu: Design documentation for expedited grace periods This commit adds design documentation for expedited grace periods. This documentation is in HTML rather than the new documentation format because (1) I have prototype documentation already in HTML, and (2) Attempting to learn the new documentation format while creating the design documentation seems likely to result in neither happening in a timely fashion. Once the design documentation is complete, we can start a conversion effort. Signed-off-by: Paul E.
