[jira] [Comment Edited] (HDFS-10958) Add instrumentation hooks
around Datanode disk IO
[ https://issues.apache.org/jira/browse/HDFS-10958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15820137#comment-15820137 ]

Cloned this as HDFS-11337 for the branch-2 backport.
The backport required many changes (due to branch divergence caused by HDFS-10637) so I'm requesting a careful review of the branch-2 patch too.
