Subject[nfsacl v2 13/16] nfs mkdir cleanup
Trond Myklebust <trond.myklebust@fys.uio.no> wrote:

[...] How about if we change the interfaces for NFS_PROTO()->mknod(), and
mkdir, so that they take a dentry argument instead of the struct qstr,
and then have them instantiate the dentry? The appended (untested) patch
tries to do this for mknod()...
