[jira] [Updated] (FLINK-31764) Get rid of numberOfRequestedOverdraftMemorySegments in LocalBufferPool

     [ https://issues.apache.org/jira/browse/FLINK-31764?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Weijie Guo updated FLINK-31764:
-------------------------------
    Description: After FLINK-31763  (was: We can changes the definition of overdraft buffer from static to dynamic: 
 * When _numberOfRequestedMemorySegments <= poolSize,_ all buffers are ordinary buffer
 * When _numberOfRequestedMemorySegments > poolSize,_ the `{_}ordinary buffer size = poolSize`{_}, and `{_}the overdraft buffer size = numberOfRequestedMemorySegments - poolSize`{_}

This allows us to remove {{{}numberOfRequestedOverdraftMemorySegments{}}}, which helps us simplify logic and maintain consistency.)
