## Synopsis

`void dentry_update_name_case (` | struct dentry * dentry,
| struct qstr * name`)`;

## Arguments

`dentry`

  dentry to be updated

`name`

  new name

## Description

Update a case insensitive dentry with new case of name.

dentry must have been returned by d_lookup with name `name`. Old and new name lengths must match (ie. no d_compare which allows mismatched name lengths).

Parent inode i_mutex must be held over d_lookup and into this call (to keep renames and concurrent inserts, and readdir(2) away).
