Seeing that fsdevel is archived, it might be worth spelling out,
actually...

Anyway, yes, something like "correct the inline descriptions of
vfs_mkdir() et.al." ought to go into commit message.  And it really
ought to cover not just vfs_mkdir() - other similar comments from
the same commit (6521f8917082 "namei: prepare for idmapped mounts")
have similar issues.  "Create a device node or file" for
vfs_mknod() probably ought to be "Create a device node or other
special file", while we are at it...
