inode to allocate the dentry for
.SH "DESCRIPTION"
.PP
This is similar to d_alloc_root.  It is used by filesystems when
creating a dentry for a given inode, often in the process of 
mapping a filehandle to a dentry.  The returned dentry may be
anonymous, or may have a full name (if the inode was already
in the cache).  The file system may need to make further
efforts to connect this dentry into the dcache properly.
.PP
When called on a directory inode, we must ensure that
the inode only ever has one dentry.  If a dentry is
found, that is returned instead of allocating a new one.
.PP
On successful return, the reference to the inode has been transferred
to the dentry.  If NULL is returned (indicating kmalloc failure),
the reference on the inode has not been released.
