 Replying to [comment:7 gabriel.hartmann]:
 > Would you consider early termination via a return statement to be
 generally desirable, or just within the scope of this particular
 situation?

 To add to what mmlr wrote, there are convenient scope-based (i.e. RAII)
 [https://dev.haiku-
 os.org/browser/haiku/trunk/headers/private/shared/AutoLocker.h AutoLocker]
 and [https://dev.haiku-
 os.org/browser/haiku/trunk/headers/private/shared/AutoDeleter.h
 AutoDeleter] classes which do not only simplify using the early-return
 style, but also help preventing programming errors like memory leaks and
 unbalanced locking. Both classes are rather flexible templates and already
 come with a bunch of handy specializations. For kernel locking needs a
 whole bunch of specializations is defined in [https://dev.haiku-
 os.org/browser/haiku/trunk/headers/private/kernel/util/AutoLock.h
 headers/private/kernel/util/AutoLock.h].
