 <p>Note on squashing: Since squash discards remote branch history, repeated PRs from the same remote branch are difficult to be merged. The workflow implies that every new PR starts with a new rebased branch. This is more important for contributors to know, rather than for committers, because if new PR is not mergeable, github would warn at the start. Please watch for dupe PRs (based on same source branches).</p>

 <p><strong>vm.extra_free_kbytes</strong>, tells the VM to keep extra free memory between the threshold where background reclaim (kswapd) kicks in, and the threshold where direct reclaim (by allocating processes) kicks in. RocketMQ uses this parameter to avoid high latency in memory allocation.</p>
