| H A D | rcu.rst | 18 sections of code with "critical sections", and the update side will wait
19 for the execution of all *currently running* critical sections before
22 The key point here is that only the currently running critical sections
23 are waited for; critical sections that are started **after** the beginning
34 removal has completed, a critical section will not be able to access
35 the old data. Therefore, critical sections that begin after removal
36 do not matter; as soon as all previous critical sections have finished,
54 Note how thread 3 is still executing its critical section when thread 2
57 that critical section.
