debugfs_rename — rename a file/directory in the debugfs filesystem
struct dentry * debugfs_rename ( | struct dentry * | old_dir, |
| struct dentry * | old_dentry, | |
| struct dentry * | new_dir, | |
| const char * | new_name); |
old_dira pointer to the parent dentry for the renamed object. This should be a directory dentry.
old_dentrydentry of an object to be renamed.
new_dira pointer to the parent dentry where the object should be moved. This should be a directory dentry.
new_namea pointer to a string containing the target name.
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.
