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.
