It sounds like iget() is what you want.

I think d_alloc_anon() may do what you want.
inode = iget(sb, inum);
if (!inode)
bail out;
if (is_bad_inode(inode)) {
iput(inode);
bail out;
}
dentry = d_alloc_anon(inode);
if (!dentry) {
iput(inode)
bail out;
}
d_alloc_anon returns an existing dentry for the inode if it can find
one. Otherwise, it will allocate a new, anonymous dentry.
