Summary: Remove LockUsageInfo
Key: HDDS-15943
URL: https://issues.apache.org/jira/browse/HDDS-15943
Project: Apache Ozone
Issue Type: Sub-task
Components: OM
Reporter: Tsz-wo Sze
Assignee: Tsz-wo Sze
- LockUsageInfo has startReadHeldTimeNanos and startWriteHeldTimeNanos
- ResourceManager has two ThreadLocal<LockUsageInfo>(s): readLockTimeStampNanos
and writeLockTimeStampNanos
-* readLockTimeStampNanos uses only startReadHeldTimeNanos
-* writeLockTimeStampNanos uses only startWriteHeldTimeNanos
Thus, we may just use ThreadLocal<Long> and remove LockUsageInfo.
