So basically this actually fixes that commit?
Fixes: d562e901f25d ("fs/ntfs3: Move ni_lock_dir and ni_unlock into ntfs_create_inode")
Or if you do not use fixes atleast use
d562e901f25d ("fs/ntfs3: Move ni_lock_dir and ni_unlock into ntfs_create_inode")
You can add these to your gitconfig
[core]
abbrev = 12
[pretty]
fixes = Fixes: %h (\"%s\")
fixed = Fixes: %h (\"%s\")
And get this annotation with
git show --pretty=fixes <sha>
Have some comments below also.

Is this really that we can lock/unlock same lock 4 times in a row in a
ntfs_set_ea? This does not feel correct.
