Subject: [PATCH 0/3] Fix MA_STATE_PREALLOC issue

Address the issue of reusing the same maple state for multiple
preallocations calls caused by MA_STATE_PREALLOC, and add a test for
this use case.

Included is a change to the testing code to reduce false positives in
the rcu race testing on faster machines.

    calls
