DEBUGFS_RENAME(9)					      The debugfs filesystem						 DEBUGFS_RENAME(9)

NAME
       debugfs_rename - rename a file/directory in the debugfs filesystem

SYNOPSIS
       struct dentry * debugfs_rename(struct dentry * old_dir, struct dentry * old_dentry, struct dentry * new_dir, const char * new_name);

ARGUMENTS
       old_dir
	   a pointer to the parent dentry for the renamed object. This should be a directory dentry.

       old_dentry
	   dentry of an object to be renamed.

       new_dir
	   a pointer to the parent dentry where the object should be moved. This should be a directory dentry.

       new_name
	   a pointer to a string containing the target name.

DESCRIPTION
       This function renames a file/directory in debugfs. The target must not exist for rename to succeed.

       This function will return a pointer to old_dentry (which is updated to reflect renaming) if it succeeds. If an error occurs, NULL will be
       returned.

       If debugfs is not enabled in the kernel, the value -ENODEV will be returned.
