>From 96fa6680e3b990633ecbb6d11acf03a161b790bd Mon Sep 17 00:00:00 2001 From: Akira Yokosawa <akiyks@xxxxxxxxx> Date: Sun, 10 May 2020 15:12:57 +0900 Subject: [PATCH RESEND 3/4] Documentation/litmus-tests: Merge atomic's README into top-level one Where Documentation/litmus-tests/README lists RCU litmus tests, Documentation/litmus-tests/atomic/README lists atomic litmus tests. For symmetry, merge the latter into former, with some context adjustment in the introduction.
