Description of changes:
There's a few places in the codebase that pass a
u32::MAXwatermark to the cursor acquire methods to simply say "try to acquire the most items possible". In the case where all items have been acquired, we still do a load and calculation. This change caps the watermark to the maximum number of items a ring can have to avoid this scenario.Testing:
I had to update the test harness, which relied on the functionality to force a fetch when passing
u32::MAX.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
