Hi, I found these opportunities for simplification as part of my work to enhance filesystem directory operations to not require an exclusive lock on the directory. There are quite a collection of users of these interfaces incluing NFS, smb/server, bcachefs, devtmpfs, and audit. Hence the long Cc line.
