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.
