This causes visible changes for users that rely on ntfs3 to serve as an

should probably be made conditional on a debug config option or similar.

I also see a

	ntfs3: Max link count 4000

message on mount which wasn't there with NTFS legacy. Is that benign
and should be suppressed too perhaps?
We need a reply from the ntfs3 maintainers here.
Those are known for taken their time to respond -- like we see here, as
nothing happened for 10 days now. Which makes we wonder: should we at
least bring the first patch from this series onto the track towards
mainline?

FWIW, quick side note: just noticed there was another report about the
"Correct links count -> 1." messages:

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

Hello Christian, Johan, all,

There is no problem in suppressing the output of any messages during mounting, like:

diff --git a/fs/ntfs3/super.c b/fs/ntfs3/super.c

                pr_info("ntfs3: Enabled Linux POSIX ACLs support\n");
        if (IS_ENABLED(CONFIG_NTFS3_64BIT_CLUSTER))

Messages like this:

-        ntfs_inode_warn(inode, "Correct links count -> %u.", names);
        rec->hard_links = cpu_to_le16(names);
        ni->mi.dirty = true;
    }

can also be suppressed for the sake of seamless transition from a remote NTFS driver. However, I believe that file system corrections should be reported to the user.
