-Subject: [PATCH] QLibrary: fix deadlock caused by fix to QTBUG-39642
-
-Commit ae6f73e8566fa76470937aca737141183929a5ec inserted a mutex around
-the entire load_sys(). We had reasoed that deadlocks would only occur if
-the object creation in instance() recursed into its own instance(),
-which was already a bug. But we had forgotten that dlopen()/
-LoadLibrary() executes initialization code from the module being loaded,
-which could cause a recursion back into the same QPluginLoader or
-QLibrary object. This recursion is benign because the module *is* loaded
-and dlopen()/LoadLibrary() returns the same handle.
-
-[ChangeLog][QtCore][QLibrary and QPluginLoader] Fixed a deadlock that
-would happen if the plugin or library being loaded has load-time
-initialization code (C++ global variables) that recursed back into the
-same QLibrary or QPluginLoader object.
-
-PS: QLibraryPrivate::loadPlugin() updates pluginState outside a mutex
-lock, so pluginState should be made an atomic variable. Once that is
-done, we'll only need locking the mutex to update errorString (no
-locking before loading).
-
