NAME

6       debugfs_rename - rename a file/directory in the debugfs filesystem
7

SYNOPSIS

9       struct dentry * debugfs_rename(struct dentry * old_dir,
10                                      struct dentry * old_dentry,
11                                      struct dentry * new_dir,
12                                      const char * new_name);
13

ARGUMENTS

15       old_dir
16           a pointer to the parent dentry for the renamed object. This should
17           be a directory dentry.
18
19       old_dentry
20           dentry of an object to be renamed.
21
22       new_dir
23           a pointer to the parent dentry where the object should be moved.
24           This should be a directory dentry.
25
26       new_name
27           a pointer to a string containing the target name.
28

DESCRIPTION

30       This function renames a file/directory in debugfs. The target must not
31       exist for rename to succeed.
32
33       This function will return a pointer to old_dentry (which is updated to
34       reflect renaming) if it succeeds. If an error occurs, NULL will be
35       returned.
36
37       If debugfs is not enabled in the kernel, the value -ENODEV will be
38       returned.
