*fsinfo not initialized, here temporary variable fsinfo here is not necessary
response->set_enablesumindir(wrapper.ProtoFsInfo().enablesumindir()); or Add method GetEnableSumInDir in class FsInfoWrapper and can use directly like response->set_enablesumindir(wrapper.GetEnableSumInDir())

use enableSumInDir->store(response.enablesumindir());
And change use enableSumInDir_ value to enableSumInDir_.load()
std::atomic::store and std::atomic::load is thread safety.

Get it! I will change afternoon.

enableSumInDir_.store(fsInfo_->enablesumindir());
FLAGS_enableCto is no longer needed here.

Pass by reference if enableSumInDir is never null. You can use //NOLINT to avoid cpplint.

What problem does this PR solve?
Issue Number: #2094
Problem Summary:
What is changed and how it works?
When the fs mount is mounted multiple times with different enableSumInDir switches, the xattr information recorded in the metadata will be inaccurate.
What's Changed:
check the mds flag in lease_executor and update for fuse client
How it Works:
just like above
Side effects(Breaking backward compatibility? Performance regression?):
