Peter Zijlstra f550466949 locking: Introduce __cleanup() based infrastructure 
[ Upstream commit 54da6a0924 ]

Use __attribute__((__cleanup__(func))) to build:

 - simple auto-release pointers using __free()

 - 'classes' with constructor and destructor semantics for
   scope-based resource management.

 - lock guards based on the above classes.
