Subject: [PATCH -next 0/3] ext4: Using scope-based resource management function

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.
