From 6a59e7f510a7b12f8b3bd768dfe569033ef07d30 Mon Sep 17 00:00:00 2001 From: Ian Gudger Date: Tue, 21 Jan 2020 19:23:26 -0800 Subject: Rename DowngradableRWMutex to RWmutex. Also renames TMutex to Mutex. These custom mutexes aren't any worse than the standard library versions (same code), so having both seems redundant.
