Quick Quiz: |
- Suppose that synchronize_rcu() did wait until all readers had completed.
- Would the updater be able to rely on this?
+ Suppose that synchronize_rcu() did wait until all
+ readers had completed instead of waiting only on
+ pre-existing readers.
+ For how long would the updater be able to rely on there
+ being no readers?
|
Answer: |
- No.
+ For no time at all.
Even if synchronize_rcu() were to wait until
all readers had completed, a new reader might start immediately after
synchronize_rcu() completed.
Therefore, the code following
- synchronize_rcu() cannot rely on there being no readers
- in any case.
+ synchronize_rcu() can never rely on there being
+ no readers.
