Hi all, This patch set is dedicated to using scope-based resource management functions to replace the direct use of lock/unlock methods, so that developers can focus more on using resources in a certain scope and avoid overly focusing on resource leakage issues. At the same time, some functions can remove the controversial goto label(eg: patch 3), which usually only releases resources and then exits the function. After replacement, these functions can exit directly without worrying about resources not being released. This patch set has been tested by fsstress for a long time and no problems were found. Thanks, Li Zetao.
