D_ADD_CI(9)			 The Linux VFS			   D_ADD_CI(9)

NAME
       d_add_ci - lookup or allocate new dentry with case-exact name

SYNOPSIS
       struct dentry * d_add_ci(struct dentry * dentry, struct inode * inode,
				struct qstr * name);

ARGUMENTS
       dentry
	   the negative dentry that was passed to the parent´s lookup func

       inode
	   the inode case-insensitive lookup has found

       name
	   the case-exact name to be associated with the returned dentry

DESCRIPTION
       This is to avoid filling the dcache with case-insensitive names to the
       same inode, only the actual correct case is stored in the dcache for
       case-insensitive filesystems.

       For a case-insensitive lookup match and if the the case-exact dentry
       already exists in in the dcache, use it and return it.

       If no entry exists with the exact case name, allocate new dentry with
       the exact case, and return the spliced entry.
