Before Creating the Bug Report

• I found a bug, not just asking a question, which should be created in GitHub Discussions.

• I have searched the GitHub Issues and GitHub Discussions of this repository and believe that this is not a duplicate.

• I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ.

Runtime platform environment

Ubuntu 20.04

RocketMQ version

5.1.3

JDK Version

1.8

Describe the Bug

Before #6336 [RIP-62] Cold Read Control, the default value of madvice is MADV_NORMAL. after RIP-62, the default value changes to MADV_RANDOM. so I think the default value of dataReadAheadEnable should be true, to keep the same with old RocketMQ versions.

Steps to Reproduce

start new version of RocketMQ.

What Did You Expect to See?

madvice MADV_RANDOM is not called.
